Abstract:
Abstract Mine drainage waters are often characterized by high concentrations of sulphates and metals as a consequence of the mining industry of sulphide minerals. The aims of this work are to prove some biological-chemical processes utilization for the mine drainage water treatment. The studied principles of contamination elimination from these waters include sulphate reduction and metal bioprecipitation by the application of sulphate-reducing bacteria (SRB). Other studied process was metal sorption by prepared biogenic sorbent. Mine drainage waters from Slovak localities Banská Štiavnica and Smolník were used to the pollution removal examination. In Banská Štiavnica water, sulphates decreased below the legislative limit. The elimination of zinc by sorption experiments achieved 84 % and 65 %, respectively.

Abstract:
The paper presents the results of the investigation of zinc leach residue (ZLR) processing by sulphatizing roasting with iron sulphates FeSO4 and Fe2(SO4)3 followed by water leaching. The elemental and phase compositions of ZLR of JSC "Chelyabinsk Zinc Plant" were studied. Based on the thermodynamic calculations using HSC Chemistry 9.9 software, the temperature ranges of the sulphatizing roasting and the required amounts of iron sulphate additives for the sulphation of zinc and copper were determined. Subsequent experiments showed that recovery rates of zinc and copper reached 99.5% and 89.1% respectively, while iron remained in the leached residue. The results have indicated a high efficiency of sulphatizing roasting to transform zinc and copper contained in ZLR from ferrite to water-soluble sulphate.

Abstract:
Redissolution of cemented cobalt from zinc sulphate solution occurs, and is a well known problem among zinc producers. A variety of mechanism of cobalt redisisolution have been proposed in the literatures, however, it is still not very well understood. The influencing factors of cobalt redissolution such as detention time, oxidation, particle size of zinc dust and copper ion have been investigated in this paper. The redissolution does not occur when very large particles are used but the redissolution of cobalt is significant from small zinc particles. The redissolution is obvious with copper ion added, while the redissolution is not occurred from the zinc sulphated solution without copper ion added. The redissolution mechanism of cobalt is obtained.

Abstract:
Morphology of Zinc Oxide (ZnO) is an important parameter to enhance the efficiency of optoelectronic devices. Morphology also plays a significant role in gas sensing properties of ZnO. In this research work, different morphologies of Zinc Oxide including nanorods, disks and flakes were obtained using Zinc Acetate, Sodium Dodecyl Sulphate and Trisodium Citrate as additives to a parent solution of Zinc nitrate hexahydrate (Zn(NO3)2·6H2O) and Hexamethylenetetramine (HMTA, (CH2)6N4) for hydrothermal growth. Use of Zinc Acetate as an additive has been rarely reported. This work presents the ability of Zinc Acetate to transform the morphology of ZnO nanorods to nanoneedles. Furthermore, in this study addition of Sodium Dodecyl Sulphate and Trisodium Citrate to the parent solution has shown potential for growing continuous granular films by the low cost and low temperature hydrothermal technique. Variation in crystallite size and band gap values with increasing concentration of Zinc Acetate, Sodium Dodecyl Sulphate and Trisodium Sulphate has been studied. Films with crystallite sizes of 7.48 nm and 6.77 nm were achieved with 5 mM Sodium Dodecyl Sulphate and 5 mM Trisodium Citrate respectively. The band gap of films produced with 5 mM Sodium Dodecyl Sulphate and with 5 mM Trisodium Citrate were 3.43 eV and 3.45 eV respectively. Therefore hydrothermal growth with Sodium Dodecyl Sulphate or Trisodium Citrate is a potential technique for obtaining granular ZnO films.

Abstract:
An extreme thermophilic, iron-sulphur oxidising bacterial culture was isolated and adapted to tolerate high metal and solids concentrations at 70?C. Following isolation and adaptation, the culture was used in a batch bioleach test employing a 5-l glass standard magnetic agitated and aerated reactor, for the bioleaching of a copper-lead-zinc collective concentrate. The culture exhibited stable leach performance over the period of leach operation and overall copper and zinc extractions higher than 97%. Lead sulphide is transformed into lead sulphate remaining in the bioleach residue due to the low solubility in sulphate media. Brine leaching of bioleach residue yields 95% lead extraction.

Abstract:
Mining effluents are major contributors to mineralization of receiving waters and can be toxic to man, animals and plants due to unacceptably high concentrations of heavy metals. A biological sulphate removal process has been developed for the treatment of sulphate-rich industrial effluents, where sulphate is converted via sulphide to sulphur in an anaerobic single-stage reactor. Ethanol is used as carbon and energy source. Sulphate was removed from acid mine water over a period of 95 days from 3000 mg/l down to less than 200 mg/l and the formed sulphides to less than 200 mg/l. The VSS value in the reactor varied between 3 and 4 g/l, resulting in a specific sulphate removal rate from 0.47 to 2.47 g SO4/(g VSS.d), while the volumetric rate was 2.5 and 8.4g SO4/(2.d) at HRT of 18 to 4.3 h. The experimental COD/sulphate ratio was between 0.55 and 0.84, which is in accordance with the theoretical value of 0.67. The experimental sulphide/sulphate ratio was less than the theoretical value of 0.33 due to the conversion of sulphate to sulphur and due to metal sulphide precipitation. Iron and copper were removed completely and aluminium, manganese and zinc to less than 4 mg/l.

Abstract:
Introduction. COVID-19 has rapidly emerged as a pandemic infection that has caused significant mortality and economic losses. Potential therapies and prophylaxis against COVID-19 are urgently needed to combat this novel infection. As a result of in vitro evidence suggesting zinc sulphate may be efficacious against COVID-19, our hospitals began using zinc sulphate as add-on therapy to hydroxychloroquine and azithromycin. Aim. To compare outcomes among hospitalized COVID-19 patients ordered to receive hydroxychloroquine and azithromycin plus zinc sulphate versus hydroxychloroquine and azithromycin alone. Methodology. This was a retrospective observational study. Data was collected from medical records for all patients with admission dates ranging from 2 March 2020 through to 11 April 2020. Initial clinical characteristics on presentation, medications given during the hospitalization, and hospital outcomes were recorded. The study included patients admitted to any of four acute care NYU Langone Health Hospitals in New York City. Patients included were admitted to the hospital with at least one positive COVID-19 test and had completed their hospitalization. Patients were excluded from the study if they were never admitted to the hospital or if there was an order for other investigational therapies for COVID-19. Results. Patients taking zinc sulphate in addition to hydroxychloroquine and azithromycin (n=411) and patients taking hydroxychloroquine and azithromycin alone (n=521) did not differ in age, race, sex, tobacco use or relevant comorbidities. The addition of zinc sulphate did not impact the length of hospitalization, duration of ventilation or intensive care unit (ICU) duration. In univariate analyses, zinc sulphate increased the frequency of patients being discharged home, and decreased the need for ventilation, admission to the ICU and mortality or transfer to hospice for patients who were never admitted to the ICU. After adjusting for the time at which zinc sulphate was added to our protocol, an increased frequency of being discharged home (OR 1.53, 95 % CI 1.12–2.09) and reduction in mortality or transfer to hospice among patients who did not require ICU level of care remained significant (OR 0.449, 95 % CI 0.271–0.744). Conclusion. This study provides the first in vivo evidence that zinc sulphate may play a role in therapeutic management for COVID-19.

Abstract:
The purpose of this research is to use a mathematical model to study the removal of calcium in the form of gypsum from zinc sulphate solution by cooling from 80ºC to 30ºC in a batch crystallizer. Factors such as cooling-rates, initial solution composition, and seed amount are analyzed. Using the simulation module developed, it is found that the removal of calcium can be improved by operating at a high temperature, which speeds up both the growth and nucleation kinetics, and produces a higher supersaturation by lowering the equilibrium molality of calcium ion in solution. Also, the addition of seed can reduce the activation energy requirement for nucleation by providing favourable surface for the formation of nuclei and enhance crystallization. Finally, experiments are performed to see if the results qualitatively support the simulation findings.

Full text
Abstract:
In this work, the kinetic and equilibrium profiles of each individual reaction step involved in the production of hematite at 200°C via oxydrolysis of ferrous sulphate in concentrated zinc sulphate media were established. Crystallization of ferrous sulphate was found to play a crucial role in the overall process due to its relatively low solubility and fast crystallization kinetics at elevated temperatures. In fact, the overall kinetics of the oxydrolysis process were found to be limited by the re-dissolution of ferrous sulphate. Pre-crystallization of ferrous sulphate prior to oxidation was found to result in enhanced overall kinetics, cutting down the required retention time from 3 to 2 hours. Enhanced kinetics were also achieved by performing oxydrolysis in two-temperature stages: a low temperature (T = 180°C) first stage with retention time >20 min and an elevated temperature (T = 200°C) second stage with retention time >100 min.
The typical composition of the hematite material produced in this work was 64.3% Fe, 1.3% S (as SO4), 0.6% Zn, and 4.6% H2O. The sulphur content was found to be predominantly (0.6--0.8%) due to formation of sodium jarosite with the remaining (0.3--0.5%) attributed to SO4 chemisorption, and (to less extent) basic ferric sulphate formation. In the absence of zinc sulphate, the majority of sulphate contamination was due to basic ferric sulphate formation. Hematite was found to form via a predominantly homogeneous nucleation mechanism with sub-micron crystallites clustered together as aggregates of 5--10 mum size and around 7 m 2/g specific surface area. In contrast, hematite produced by direct hydrolysis of ferric sulphate possessed one order of magnitude higher specific surface area. As for the industrial hematite product, its composition was found to be 52.6% Fe, 4.6% S, 1.0% Zn, and 8.8% H2O. The sulphur contamination in the industrial product was mainly due to co-precipitation of jarosite and basic ferric sulphate compounds. Hydrothermal trans-formation of the industrial hematite product at elevated temperatures (>200°C) and retention time of >60 min with solids loading as high as 16 wt.% proved to be effective in reducing the sulphur content to less than 1%.

Full text
Abstract:
The purpose of the present work was to remove selectively manganese from a neutral leach zinc-rich solution at 80ºC using the gas mixture of sulphur dioxide (SO2) and oxygen (O2) as oxidizing agent. In order to determine the optimum conditions for manganese removal using SO 2/O2, several semi-batch experiments were performed, where the effects of pH, ORP, SO2/O2 ratio, mixing intensity, etc. were investigated. Results of these tests showed that SO2/O 2 was a fast and effective oxidant for removing manganese down to ppm level provided that the appropriate reactor design, agitation and SO 2/O2 ratio were employed. In an attempt to improve the precipitate's characteristics, e.g. crystallinity and solid/liquid separation, a new technique called Step-Wise Oxidative Precipitation (S.W.O.P) was investigated using a two-reactor continuous circuit employing pH and ORP control and precipitate recycling. These tests revealed that a birnessite-like phase with general formula (Na0.7Ca0.3)Mn7O14·2.8H 2O was produced with co-precipitation of a significant amount of zinc apparently via substitution. The applied technique (S.W.O.P combined with recycling) proved effective in producing dense particles but not on lowering zinc losses. The biggest advantage of this novel oxidation technique was the total elimination of scaling. (Abstract shortened by UMI.)

Abstract:
Giardia intestinalis is the most common parasite found in dogs and cats. It is traditionally diagnosed using a microscope. These methods include direct immunofluorescence, DIF, and zinc sulphate centrifugal flotation, ZnSO4 C-flotation. However, there are commercially available SNAP tests such as the FASTest® GIARDIA strip that is often used by dogs and cats owner to detect Giardia. The aim of this study was to compare the sensitivity, cost and labor intensity of these three methods for detection of Giardia. To investigate this, 150 samples from dogs and cats were examined at the National Veterinary Institute in Sweden. The samples were a mixture of diarrheic and non-diarrheic stool. Of the 150 stool samples 100 samples were examined with FASTest® GIARDIA strip while 150 samples were examined with DIF and ZnSO4 C-flotation. The results indicated that FASTest® GIARDIA strip had a sensitivity of 66.18 %, a cost of 100 Swedish crowns (SEK) per sample and was the easiest test to use. ZnSO4 C-flotation had a sensitivity of 89.90 %, cost 418.75 SEK and took about 15 minutes to perform. DIF had 100 % sensitivity and specificity and due to that it was used as a standard reference method. The cost for DIF was 300 SEK and took more than an hour to perform per sample. The conclusion from this study is that, FASTest® GIARDIA strip is not a recommended test for detection of Giardia despite their low cost and easiness to use. DIF and ZnSO4 C-flotation remain a better diagnostic option for detection of Giardia.

Abstract:
In a green house pot experiment, the effects of three amendments, sulphur (S), ammonium sulphate ((NH4)2SO4) and ethylenediaminetetracetic acid (EDTA) were tested for phytoextraction of Cd and Zn by rapeseed (Brassica napus L.). Elemental sulphur was applied as 20.00, 60.00, and 120.00 mg.kg−1 soil. EDTA was tested at a dose of 585.00 mg.kg−1 soil, and (NH4)2SO4) at a rate of 0.23 mg.kg−1 soil. All treatments received a base fertilization (Hogland) before sowing. Plants were harvested after 51 days of growth and shoot dry matter and soil samples were analysed for metal contents. All amendments caused a significant increase in Cd and Zn contents in plant shoots of all treatments than control treatment. Further, EDTA was most effective for extraction metals concentrations in shoot biomass but the plants showed significant signs of toxicity and yield were severely depressed. The addition of sulfur favorably influenced plant biomass production. The fertilized ammonium sulfate treatment resulted in the highest phytoextraction of Cd and Zn and the amounts of these metals accumulated in plant shoot exceeded by a factor of 4 and 3 respectively. Finally, Brassica napus could be used for soil remediation keeping its other uses which will make the contaminated site income generating source for the farmers.

Abstract:
A tandem purification procedure was developed by a combination of metal chelate and affinity chromatography. The conditioned medium from different cell lines producing tissue plasminogen activator was first chromatographed on a zinc chelate-agarose column equilibrated with low ionic strength buffer. After thorough washing, the column was connected to a lysine-agarose column, previously equilibrated with the same buffer. Tissue plasminogen activator was eluted from the zinc chelate column by a gradient of imidazole and the effluent was allowed to flow through lysine-agarose matrix. The two columns were disconnected and after thorough washing, the bound enzyme from lysine-agarose column was eluted with a linear gradient of potassium thiocyanate in the equilibration buffer. This method resulted in a purification factor which varied between 40 to 110 fold. The purity of the isolated enzyme was assessed by sodium dodecyl sulphate-gel electrophoresis and fibrin zymography. The chromatographic procedure described provides a novel method for the rapid purification of tissue plasminogen activator to a high degree of purity.

Abstract:
A proteolytic product of vWf termed fast migrating protein (vWf:FMP) has been identified using crossed immunoelectrophoresis (CIE) in normal serum and in the plasma from patients with disseminated intravascular coagulation (DIC). A fragment of vWf antigen (vWf:Ag) migrating to a similar position on CIE as vWf:FMP results from digestion of vWf:Ag with polymorphonuclear cells (PMNC). Since parallels exist between the conditions for generation of vWf:FMP by PMNC and elastase release by these cells the effect of purified elastase from porcine pancrease on vWf was investigated.VWf was purified from plasma using polyethylene glycol, ammonium sulphate and zinc acetate precipitation, high speed centrifugation and elution from column of Sepharose 4B-CL. A fraction rich in vWf was radiolabelled with 125-Iodine to spike the purified preparation of vWf in order to increase the sensitivity of the protein detecting systems.A mixture of radiolabelled and non-labelled purified vWf was incubated with elastase at concentrations ranging from 2.5 to 40 U/ml for periods of 0-48 hours. Modifications of the structure were assessed by SDS-agarose multimeric analysis, SDS-polyacrylamide electrophoresis and CIE. Alterations of function were quantitated by antigen levels, ristocetin (RCof) and botrocetin (BCoF) cofactor assays and a binding assay to fixed washed platelets in the presence of ristocetin or botrocetin.These investigations show, 1. all but the highest molecular weight multimers of vWf are present when elastase has cleaved vWf such that no intact 240K subunit is present. 2. an intact 240K subunit is not essential for RCoF and BCoF activity or for ristocetin or botrocetin induced binding to platelets.
