Abstrak: Penelitian ini bertujuan untuk mengetahui peranan Amonium thiosulfat dan Sodium thiosulfat sebagai bahan pengkhelat pada proses Fitoremediasi dengan menggunakan tanaman Paspalum conjugatum (Rumput Paitan). Metode yang digunakan dalam penelitian ini adalah metode eksperimental yang dilakukan di lapangan pada bulan Mei sampai Juli 2017. Penelitian dirancang menggunakan Rancangan Acak Kelompok (RAK) dengan variasi perlakuan: PAT1 = pemberian Amonium thiosulfat sebanyak 1 gr, PAT2 = pemberian Amonium thiosulfat sebanyak 2 gr, PST1 = pemberian Sodium thiosulfat sebanyak 1 gr, PST2 = pemberia Sodium thiosulfat sebanyak 2 gr. Setiap perlakuan diulang sebanyak 3 kali sehingga diperoleh 12 unit percobaan. Parameter yang diamati dalam penelitian ini meliputi konsentrasi Hg pada tanaman, berat berangkasan, dan tinggi tanaman. Data hasil pengamatan dianalisis dengan menggunakan standar deviasi mean. Bahan pengkhelat Amonium thiosulfat lebih tinggi mengikat Hg di bandingkan dengan Sodium thiosulfat. Konsentrasi kadar total Hg tertinggi terdapat pada perlakuan Amonium thiosulfat dosis 2 gr/15 liter sebesar 1137,87 ppm. Semakin tinggi konsentrasi Hg pada tanah mengakibatkan pertumbuhan tanaman terhambat.Abstract: Ammonium thiosulfate and Sodium thiosulfate as chelating material in the Phytoremediation process using Paspalum conjugatum (Paitan Grass). The method used in this study is an experimental method conducted in the field from May to July 2017. The study was designed using Randomized Block Design (RBD) with a variety of treatments: PAT1 = giving 1 gr Ammonium thiosulfate, PAT2 = giving 2 gr Ammonium thiosulfate giving, PST1 = giving 1 gr Sodium thiosulfate, PST2 = giving 2 grams of Sodium thiosulfate. Each treatment was repeated three times to obtain 12 experimental units. The parameters observed in this study include the concentration of Hg in plants, the weight of stature, and plant height. Observation data were analyzed using the standard deviation of the mean. The chelating agent Ammonium thiosulfate is higher in binding to Hg compared to Sodium thiosulfate. The highest concentration of total Hg was found in Ammonium thiosulfate treatment with a dose of 2 gr / 15 liters of 1137.87 ppm. The higher the concentration of Hg on the soil resulted in stunted plant growth.

Nephrotoxicity frequently limits the dose of cisplatin to less than 120 mg/m2 per injection. Sodium thiosulfate is a neutralizing agent for cisplatin that protects against renal damage. To determine whether injection of thiosulfate would permit larger doses of cisplatin to be administered, a fixed 9.9-g/m2 dose of thiosulfate was given intravenously over three hours concurrently with escalating doses of cisplatin. Cisplatin was administered over the last two hours of the thiosulfate infusion. Using this technique, it was possible to escalate the cisplatin dose to 225 mg/m2 before dose-limiting toxicities were encountered. Comparison of cisplatin pharmacokinetics in patients treated with 202.5 mg/m2 plus thiosulfate to those in patients treated with 100 mg/m2 without thiosulfate indicated that there were no changes in the elimination rate constant, volume of distribution, or total body clearance of cisplatin. The total drug exposure for the plasma was approximately twofold at the higher cisplatin dose. This study demonstrates that concurrent administration of thiosulfate permits at least a twofold increase in dose and total exposure to cisplatin.

Sodium nitroprusside is an antihypertensive agent used frequently in the critical care setting. Recently, the Food and Drug Administration (FDA) published a report that led to a labeling change emphasizing the pharmacokinetics of nitroprusside with metabolism to highly toxic cyanide. Although evidence validates that cyanogenesis occurs with nitroprusside administration, prevention and treatment of cyanide poisoning is rarely instituted in clinical practice. Simultaneous infusion of thiosulfate with nitroprusside provides the sulfur donor necessary to prevent cyanide accumulation. Cyanide combines with thiosulfate to form the less toxic sodium thiocyanate, which is then excreted. A 10:1 ratio of nitroprusside to thiosulfate in the infusion eliminates the possibility of cyanide intoxication without altering the efficacy of nitroprusside.

Due to the disadvantages of physiochemical methods for sulfidic spent caustic treatment, attentions are drawn to the environmental-friendly biotreatments including sulfur-oxidizing halo-alkaliphiles.Thioalkalivibrio versutusDSM 13738 was grown at alkaline (pH10) autotrophic medium with sodium carbonate/bicarbonate as the sole source of carbon and amended with sodium thiosulfate as the electron and energy source. The effect of various parameters including temperature (25-40 °C), pH (8-11), NaCl concentration (0.5-5 % w/v) and sodium thiosulfate concentrations (100-750 mM) was evaluated on bacterial growth and thiosulfate removal. This strain could eliminate sodium thiosulfate at very high concentrations up to 750 mM. The results showed that the highest specific growth rate was pH 9.5 and thiosulfate removal ofThioalkalivibrio versutusoccurred at pH 10.5. The optimum salt concentration for thiosulfate removal was 2.5 % w/v and 5 % NaCl and specific growth rate elevated 2.5% w/v. It was also specified that this strain thrives occurred in 37 °C and at 35 and 37 °C higher removal of thiosulfate. Following chemical oxidation of sulfide to thiosulfate, application ofThioalkalivibrio versutuscould be promising for spent caustic treatment. Since thiosulfate is utilized as an energy source, highest removal efficiency occurred at marginally different conditions compared to optimal growth.

Thiosulfate oxidation and mixotrophic growth with succinate or methanol plus thiosulfate was examined in nutrient-limited mixotrophic condition for Methylobacterium oryzae CBMB20, which was recently characterized and reported as a novel species isolated from rice. Methylobacterium oryzae was able to utilize thiosulfate in the presence of sulfate. Thiosulfate oxidation increased the protein yield by 25% in mixotrophic medium containing 18.5 mmol·L–1of sodium succinate and 20 mmol·L–1of sodium thiosulfate on day 5. The respirometric study revealed that thiosulfate was the most preferable reduced inorganic sulfur source, followed by sulfur and sulfite. Thiosulfate was predominantly oxidized to sulfate and intermediate products of thiosulfate oxidation, such as tetrathionate, trithionate, polythionate, and sulfur, were not detected in spent medium. It indicated that bacterium use the non-S4intermediate sulfur oxidation pathway for thiosulfate oxidation. Thiosulfate oxidation enzymes, such as rhodanese and sulfite oxidase activities appeared to be constitutively expressed, but activity increased during growth on thiosulfate. No thiosulfate oxidase (tetrathionate synthase) activity was detected.

The sulfite pulping process is today practised in only a small number of pulp mills around the globe and the number of sulfite mills that use sodium as the base (cation) is less than five. However, due to the increasing interest in the wood based biorefinery concept, the benefits of sulfite pulping and especially the sodium based variety, has recently gained a lot of interest. It was therefore considered to be of high importance to further study the sodium based sulfite process to investigate if its benefits could be better utilized in the future in the production of dissolving pulps. Of specific interest was to investigate how the pulping conditions in the initial part of the cook (≥ 60 % pulp yield) should be performed in the best way. Thus, this thesis is focused on the initial phase of single stage sodium bisulfite cooking of either 100 % spruce or 100 % pine wood chips. The cooking experiments were carried out with either a lab prepared or a mill prepared cooking acid and the temperature and cooking time were varied. Activation energies for different wood components were investigated as well as side reactions concerning the formation of thiosulfate and sulfate.
Single stage sodium bisulfite cooking was carried out on either spruce or pine wood chips to investigate the influence of several process parameters in the initial phase of such a cook i.e. between 100 % and 60 % pulp yield. The cooking experiments were carried out with either a lab prepared or a mill prepared cooking acid and the temperature and time in the initial stage were varied. The influence of dissolved organics and inorganics components in the cooking liquor on the final pulp properties and side reactions were investigated. The impact of temperature and time on the pulp components were analyzed with respect to carbohydrates, lignin, extractives and thiosulfate. Kinetic equations were developed and the activation energies for delignification and carbohydrate dissolution were calculated using the Arrhenius equation. It was found that if using a mill prepared cooking acid, this had a beneficial effect with respect to side reactions, better extractives removal and higher pH stability during the cook, compared to a corresponding cook with a lab prepared cooking acid. Cooking with mill prepared and lab prepared cooking acids showed the same behaviour with respect to delignification and carbohydrate degradation, but the lab acid experiments resulted in a higher thiosulfate formation during the cook. The cellulose yield was not affected at all during the initial phase of the sulfite cook verifying earlier results by other researchers. The temperature had an influence on both the delignification rate and the rate of hemicelluloses removal.  The corresponding activation energies were found to increase in the following order; cellulose, xylan, glucomannan and lignin.

L’objectif global de cette thèse était d’étudier, à partir de la cohorte des patients du centre de référence PXE du CHU d’Angers, différente aspects du phénotype cardiovasculaire (CV) du PXE. Ainsi, dans un premier travail, nous avons pu montrer dans l’étude GOCAPXE, que les calcifications ectopiques seraient un processus actif pouvant être détecté par une imagerie moléculaire utilisant un traceur spécifique de l’activité ostéoblastique, le 18-Fluorure de Sodium (18F-NaF); que ce processus était détectable avant même que ces calcifications ne soient visibles par les techniques d’imageries classiques; que ce processus était localisé aux zones habituellement lésées dans le PXE : les plis de flexion et le cou pour la peau et l’artère fémorale superficielle pour le vaisseau. Cette technique mériterait d’être validée dans une étude longitudinale et son rôle en tant biomarqueur diagnostique et de suivi serait ainsi envisageable. Le deuxième travail de cette thèse a été d’étudier les conséquences morphologiques et fonctionnelles d’une augmentation chronique de la pression artérielle chez les patients PXE. Cette question était pertinente car dans la littérature, la question d’une hypertension artérielle (HTA) chez les PXE reste controversée. Nous avons ainsi montré pour la première fois que dans un modèle d’HTA induite par le Deoxycorticostérone (DOCA)-Salt chez la souris Abcc6-/- cette augmentation de la pression artérielle induisait un remodelage CV avec à la fois de la fibrose et des calcifications dystrophiques. Les résultats de cette étude suggèrent la nécessité d’un contrôle optimal de la pression artérielle chez les patients PXE. Le troisième travail de cette thèse a été de caractériser une lésion de la carotide interne détectée avec une fréquence élevée dans la cohorte angevine. Nous avons pu montrer que cette anomalie était une hypoplasie de la carotide interne d’origine probablement congénitale. Chez les patients de la cohorte angevine, cette lésion était associée à des anévrismes intracrâniens mais nous n’avons pas retrouvé d’association avec la survenue d’accident vasculaire cérébral. Ainsi, les résultats de cette étude invitent les praticiens prenant en charge des patients PXE à la rechercher systématiquement dans le bilan vasculaire d’un patient PXE. Si une telle lésion est retrouvée, une imagerie vasculaire intracrânienne devrait être proposée à la recherche d’anévrismes et leur prise en charge discuté en concertation multidisciplinaire. Enfin, le dernier travail a permis de montrer qu’un traitement systémique par le Thiosulfate de Sodium (STS), utilisé dans la calciphylaxie rénale, était efficace sur la régression des calcifications artérielles et cutanées chez une jeune garçon ayant un phénotype CV gravissime résultant de la combinaison délétères de plusieurs gènes pathogènes du spectre PXE Ce traitement mériterait d’être validé dans un essai thérapeutique chez l’humain mais aussi la démonstration de ses mécanismes d’action dans le modèle murin Abcc6-/-. Nous suggérons d’utiliser ce traitement en cas de PXE sévère et rapidement progressif notamment sur le plan vasculaire. Au terme de ce travail de thèse, nous avons montré que le gène ABCC6 était impliqué dans le remodelage vasculaire à la fois au niveau développemental (Hypoplasie Carotidienne) mais aussi acquis (Fibrose, Calcification Cardiaque Dystrophique). Nous avons montré aussi que les calcifications dans le PXE étaient tissus et localisations spécifiques, que ces calcifications étaient actives. Enfin nous avons ouvert la porte à un traitement des formes graves du PXE avec le Thiosulfate de Sodium. Une approche thérapeutique multimodale ciblant plusieurs mécanismes concourant aux calcifications seraient judicieux à évaluer dans les futurs essais cliniques
Since the discovery of the ABCC6 gene in 2000, mutations are at the origin of PseudoxanthomeElastic (PXE), knowledge of genetics, pathophysiology, phenotypic characterizations have has mademajor advances, notably with the Discovery in 2013 of the fundamental role of Pyrophosphateinorganic (PPi) as a deficient anti‐calcifying factor in patients. The overall goal of this thesis was tostudy, from the cohort of patients at the center of PXE reference of the CHU d'Angers, differentaspects of cardiovascular phenotype (CV) of PXE. Thus, in a first work, we were able to show in thestudy GOCAPXE, that ectopic calcifications would be a active process that can be detected by imagingUsing a specific activity tracer Osteoblastic, 18‐sodium fluoride (18F‐NaF); that this process wasdetectable even before these calcifications are not visible by conventional imaging techniques; thatthis process was localized to areas usually injured in the PXE: flexion folds and neck for skin and thesuperficial femoral artery for the vessel. This technique should be validated in a study longitudinaland its role as a diagnostic biomarker In this way, monitoring and monitoring could be considered.The second work of this thesis was to study the morphological consequences and functional of achronic increase in blood pressure in PXE patients. This question was relevant because in theliterature, the question of a high blood pressure (hypertension) in PXE remains controversial. Wehave thus shown for the first time that in a model of HTA induced by the Deoxycorticosterone(DOCA)‐Salt in Abcc6‐/‐ this increase in blood pressure led to a CV remodeling with both fibrosis andcalcifications dystrophic. The results of this study suggest need for optimal control of blood pressurein patients. The third work of this thesis was to characterize a lesion of the internal carotid detectedwith high frequency in the Angevine cohort. We have could show that this abnormality washypoplasia of the Probably congenital internal carotid. In the patients of the angevine cohort, thislesion was associated with intracranial aneurysms but we have not found in association with theoccurrence of vascular accident brain. Thus, the results of this study invite practitioners supportingPXE patients to search for it systematically in the vascular balance of a PXE patient. If such a lesion isfound, vascular imaging Intracranial should be proposed to research Aneurysms and theirmanagement discussed in consultation multidisciplinary. Finally, the latest work has made it possibleto show that systemic treatment with Thiosulphate Sodium (STS), used in renal calciphylaxia, waseffective on the regression of arterial calcifications and skin in a young boy with a phenotype CVGravel resulting from the deleterious combination of several pathogenic genes of the PXE spectrumThis treatment would deserve be validated in a human therapeutic trial but also the demonstrationof its mechanisms of action in the Abcc6‐/‐murin model. We suggest using this treatment for severeand rapidly progressive PXE especially on the vascular plane.At the end of this thesis work, we showed that the ABCC6 gene was involved in vascular remodelingat both at the developmental level (Carotid Hypoplasia) but also acquired (Fibrosis, CardiacCalcification Dystrophic). We also showed that calcifications in PXE were tissues and locationsspecific, that these calcifications were active. Finally we have opened the door to a treatment ofsevere forms of PXE with Sodium Thiosulphate. An approach multimodal therapy targeting multiplemechanisms this would be useful to evaluate in future clinical trials

Single stage and two-stage sodium sulfite cooking were carried out on either spruce, pine or pure pine heartwood chips to investigate the influence of several process parameters on the initial phase of such a cook down to about 60 % pulp yield. The cooking experiments were carried out in the laboratory with either a lab-prepared or a mill-prepared cooking acid and the temperature and time were varied. The influences of dissolved organic and inorganic components in the cooking liquor on the final pulp composition and on the extent of side reactions were investigated. Kinetic equations were developed and the activation energies for delignification and carbohydrate dissolution were calculated using the Arrhenius equation. A better understanding of the delignification mechanisms during bisulfite and acid sulfite cooking was obtained by analyzing the lignin carbohydrate complexes (LCC) present in the pulp when different cooking conditions were used. It was found that using a mill-prepared cooking acid beneficial effect with respect to side reactions, extractives removal and higher stability in pH during the cook were observed compared to a lab-prepared cooking acid. However, no significant difference in degrees of delignification or carbohydrate degradation was seen.  The cellulose yield was not affected in the initial phase of the cook however; temperature had an influence on the rates of both delignification and hemicellulose removal. It was also found that the  corresponding activation energies increased in the order:  xylan, glucomannan, lignin and cellulose. The cooking temperature could thus be used to control the cook to a given carbohydrate composition in the final pulp. Lignin condensation reactions were observed during acid sulfite cooking, especially at higher temperatures. The LCC studies indicated the existence of covalent bonds between lignin and hemicellulose components with respect to xylan and glucomannan. LCC in native wood showed the presence of phenyl glycosides, ϒ-esters and α-ethers; whereas the α-ethers  were affected during sulfite pulping. The existence of covalent bonds between lignin and wood polysaccharides might be the rate-limiting factor in sulfite pulping.
The sulfite pulping process is today practised in only a small number of pulp mills around the globe and the number of sulfite mills that use sodium as the base (cation) is less than five. However, due to the increasing interest in the wood based biorefinery concept, the benefits of sulfite pulping and especially the sodium based variety, has recently gained a lot of interest.

Activation energies for different wood components were investigated as well as side reactions concerning the formation of thiosulfate. LCC (Lignin carbohydrates complexes) studies were carried out to investigate the influence of different cooking conditions on lignin carbohydrate linkages.

Recently copper has been used to replace Al metallization in ultra large scale integrated (ULSI) technology because of low resistivity and stress-induced voiding. Copper can be deposited by physical vapor deposition, thermal-induced reflow, chemical vapor deposition, electroplation and electroless deposition. Electroless copper deposition can be processed with high speed in mass production. Therefore, Electroless copper deposition would be a potential technology for the manufacture of ULSI. The main purpose of this research is to investigate the effects of sodium thiosulfate on the plating rate, surface morphology, crystal structure, chemical composition and resistivity of copper deposition. And to study mechanism of sodium thiosulfate on electroless copper deposition by the electrochemical impedance spectroscopy, the double layer capacitance and resistance of the working electrode were calculated. The equivalent electronic circuit for the electrochemical cell of electroless copper deposition will be obtained by simulation to further understand the effect of additive on electroless copper deposition. The results show that with addition of sodium thiosulfate as additive the borate buffered electroless copper plating solutions was stabilized and the plating rate was decreased from 14.68 μm/hr to 4.18 μm/hr with addition of 20 mg/l sodium thiosulfate, surface morphology of copper deposition was smoothed, the texture coefficient remained the same within experimental error, the size of the crystal was decreased, the oxygen content of copper deposition was decreased, the resistivity was decreased from 51.49 μΩ-cm to 2.36 μΩ-cm with addition of 20 mg/l sodium thiosulfate in plating solution.The charge transfer resistance and double layer capacitance of the working electrode were increased.

Sodium thiosulfate pentahydrate-catalyzed per-O-acetylation and promoted glycosyl disulfide bond formation of carbohydrates can be tuned by adjusting the reaction medium. In this study, the per-O-acetylation of free sugars was conducted by using the catalytic amounts of sodium thiosulfate pentahydrate and stoichiometric amounts of acetic anhydride under solvent-free conditions and obtained the peracetylated glycosides with higher β/α ratio. Moreover, the installed acid-labile protecting group of glycosides were also investigated for acetylation and obtained high reaction yields. We even found that sodium thiosulfate pentahydrate can be recycle used. In addition, the S-deacetylation of glycosyl 1-(or 6-)thioacetate was proceeded by using sodium thiosulfate pentahydrate and surprisingly the glycosyl disulfide products were obtained with moderate to good reaction yields. Also, the fully deprotected glycosyl disulfide products were obtained in long reaction time.

OBJECTIVE: The aims of this study to evaluate the effect of sodium thiosulfate with SDF on shear bond strength and Microtensile bond strength for composite and biodentine Activa restorative materials, microhardness of dentin and color stability of dentin surface. METHODS: One hundred and twenty-three extracted human permanent molar teeth were used in this study. For Specimens were distributed into eight groups (n=10) for microtensile bond strength (MTBS) and Shear bond strength (SBS) testing. (1) Control: Dentin rinsed with deionized water and restored with Composite restoration. (2) SDF: Dentin treated with 38% SDF and restored with Composite restoration. (3) SDF-KI: Dentin treated with SDF and KI and restored with Composite restoration. (4) Na2S2O3: Dentin treated with SDF and Na2S2O3 and restored with Composite restoration. (5) Control: Dentin rinsed with deionized water and restored with Activa restoration. (6) SDF: Dentin treated with 38% SDF and restored with Activa restoration. (7) SDF-KI: Dentin treated with SDF and KI and restored with Activa restoration. (8) Na2S2O3: Dentin treated with SDF and Na2S2O3 and restored with Activa restoration. MTBS beams were prepared from each specimen after 24 hours and tested with Microtensile tester. Meanwhile, SBS specimens were stored for 24 hours after placement of restorative materials than tested with a universal testing machine (Instron 5566A). In addition, the type of failure was recorded. For micro-hardness test, Specimens were distributed into 3 groups (n=3). (1) SDF: Dentin treated with 38% SDF. (2) SDF-KI: Dentin treated with SDF and KI. (3) Na2S2O3: Dentin treated with SDF and Na2S2O3. The Vickers Hardness Number (VHN) was obtained in three phases for each specimen. (1) Sound dentin: After exposed the dentin surface. (2) demineralized dentin: After immersed the specimens into the demineralized solution for three days. (3) Treated dentin: After one week of application of dentin treatment agent to demineralized dentin surface. For dentin color assessment, Specimens were distributed into 4 groups (n=4). The color of dentin was assessed by using Vita EasyShade and the readings were taken at different time points for each specimen: T0= Pre-treatment; T1= after dentin treatment by one day; T7= after dentin treatment by one week; and T14= after dentin treatment by two weeks. CONCLUSIONS: • The microhardness of demineralized dentin improves after the application of SDF, SDF/Na2S2O3, and SDF/KI. Unaccompanied SDF application permitted significantly higher microhardness values than SDF/KI and SDF/Na2S2O3 application. • Application of SDF and SDF/KI negatively impact the bond strength of composite and Activa Biodentine restorative materials to sound dentin. Meanwhile, the application of Na2S2O3 immediately after SDF application improved the bond strength of composite and active restorative materials to sound dentin. • SDF/KI and SDF/Na2S2O3 can significantly reduce the staining effect of SDF on sound dentin.

Abstract For a successful hydraulic fracturing operation, shear recovery and thermal stability are critical in terms of successful fracture creation and proppant placement. Sodium thiosulfate is one of the most commonly used gel stabilizers in fracturing gel. This paper reported a well in sulfur-free gas reservoir produced hydrogen sulfide as much as 20000ppm after hydraulic fracturing operation. A series of experiments were carried out to reveal the mechanism of hydrogen sulfide production. Results showed that in solution with PH less than 6.5, when the temperature is higher than 119 degrees Celsius, sodium thiosulfate will react with hydrogen ions to generate hydrogen sulfide. In this complex reaction, there is also precipitation of elemental sulfur, which may block the pores of the reservoir and thence counteract the effect of hydraulic fracturing. The acidic solution in a fractured well is from (1) Spent acid left downhole due to pre-acid used to reduce fracturing pressure, and (2) Sulfuric acid produced by the decomposition of ammonium persulfate which is used as gel breaker at high temperature. This paper proposed two solutions to the problem of high-temperature fracturing fluids,one is to use a sulfur-free temperature stabilizer,and the other is to create a non-acid downhole environment. The opinions provided by this paper can help the operators reduce the risk of the damage of hydrogen sulfide and protect the integrity of the well of high temperature fracturing wells.

Bubble column is regarded as a kind of wet filtration method. The solution used in filter containment vented system is composed of a large amount of inorganic salt including sodium hydroxide and sodium thiosulfate. Solution with high inorganic salt concentration is more viscous and has stronger surface tension than distilled water. This property has significant effect on bubble size and bubble deformation during formation process. Besides bubble coalescent is suppressed with inorganic concentration increase. This phenomenon is found to possess influence on bubble formation regime when bubble formation regimes belong double, paring and injection regime. The existence of aerosol in solution is another factor that has obvious effect on bubble formation regime and the transition velocity between regimes. This paper apply high speed camera to study the influence rule of inorganic salt and aerosol concentration on bubble size during formation and formation regimes transition.

The growing demand for natural gas and oil, as energy sources, has driven industry’s need for ever-increasing strength levels in oil and gas transmission pipeline materials in order to achieve safe and economic transportation. The current world trend points to the use of pipes with larger diameters and thinner wall thicknesses, operating under high pressure. In addition, pipeline steels for sour service must exhibit good Hydrogen Induced Cracking (HIC) and Sulphide Stress Corrosion Cracking (SSCC) resistance. This study evaluates the susceptibility of API 5L-X80 girth welds to SSCC and Hydrogen Embrittlement (HE). Slow strain rate tensile (SSRT) tests and Hydrogen Permeation tests were performed at room temperature, in different acidic environment containing sodium thiosulfate solutions. Most of the SSRT tests undertaken in solution, showed a loss of ductility and a decrease in the reduction of area, as compared with tests conducted in air. The susceptibility to HE and potentially SSCC was evidenced by a reduction in ductility in the SSRT tests and an increase in the hydrogen permeation current values, for almost all welded joints. This was observed with greater intensity for the more acidic test solutions (pH = 3.4), while for the less acidic test solutions (pH = 4.4) little loss of ductility was observed and the hydrogen permeation current remained at values close to zero, indicating little or no permeation of hydrogen through the metal for the testing times applied. The behaviour exhibited by the samples tested in the more acidic solutions was attributed to the dissolution of material from the sample together with hydrogen embrittlement. These results confirmed that the use of sodium thiosulfate solutions to generate H2S, permits the study of phenomena related to SCC in environments containing sulphides.
