Abstract:
Background Proteinuria is a condition when protein is found in urine, a common symptom in children with renal disorders. Proteinuria can also be found in nonnal children and in those with non-renal disorders. A high sensitivity test is needed to detect proteinuria. Spectrophotometry has been used as a standard to detect proteinuria, however, it is expensive and not readily available in health clinics. We tested the use of20% sulfosalicylic add to detect proteinuria, and compared it to spectrophotometry. The sulfosalicylic add test is inexpensive, rapid, and easily performed in primary community health centers.Objective To compare 2 0 % sulfosalicylic acid test t o spectrophotometry as a diagnostic test for proteinuria.Methods We conducted a cross-sectional study in Adam Malik Hospital from September 2009 until December 2009. Inclusion criteria were children aged 3 to 18 years who experienced kidney disease. We collected 24 hour urine specimens from 55 children by consecutive sampling. Urine specimens were tested for proteinuria by 20% sulfosalicylic acid test and spectrophotometry.Results Sensitivity and specificity of 20% sulfosalicylic acid test compared to spectrophotometry were 88.1 % and 69.2%, respectively, with a positive predictive value and a negative predictive value of 90.2% and 64.3%, respectively.Conclusion The sulfosalicylic acid test had low sensitivity and specificity for detecting proteinuria, but it was more practical and less expensive compared to spectrophotometry.

Abstract:
Introduction. The existence of proteinuria may be overlooked by applying the test strips. The aim of this study has been to determine the discrepancy between the findings of proteinuria detected by test strips when compared to the results of its testing with the sulfosalicylic acid. Material and Methods. The study sample consisted of 1106 subjects, who were divided into the proteinuria positive (test strips showed the presence of isolated proteinuria), and proteinuria negative group (microscopic examination revealed the presence of >10 fresh red blood cells/?L, and/or >1 dysmorphic erythrocyte/?L, and/or >10 leukocytes/?L, and/or> 1 cylinder, and/or >1 nonsquamous epithelial cells/?L, and/or >100 bacteria/?L). Both groups had the urine tested with sulfosalicylic acid. The chemical and microscopic examination of the urine was done by the analyzer LabUMat-UriSed. Results. Proteinuria was confirmed with the sulfosalicylic acid test in 96.5% of subjects from group 1 and in 85.3% of subjects from group 2. Among the patients with the negative finding of proteinuria on the test strip and with the positive sulfosalicylic acid test there was a significantly higher number of those with pathological findings of erythrocytes, leukocytes, bacteria and cylinders in the urine when compared to those of the same group with negative sulfosalicylic acid test. Conclusion. Sulfosalicylic acid test should be performed in cases of pathological microscopic findings in the urine in case of the presence of >10 fresh erythrocytes/?L and/or >1 dysmorphic eryth?rocyte/?L and/or >10 leukocytes/?L and/or >1 cylinder (except hya?line) and/or >1 nonsquamous epithelial cells/?L and/or >100 bacteria/?L even if the test strip examination is negative for proteinuria.

Abstract:
By doping three complex dopants in different molar ratio, a series of polypyrroles doped with 9, 10-anthraquinone-2-sulfonic acid sodium, 5-sulfosalicylic acid and toluene-4-sulfonic acid were synthesized by polymerizing the monomer pyrrole in aqueous solution of ferric chloride. The resulting polypyrroles were characterized with the four-probe and laser light scattering, respectively. Our results indicate that optimized value of conductivity reached to 6683 S/m when the molar ratio of anthraquinone-2-sulfonic acid sodium to 5-sulfosalicylic acid to toluene-4-sulfonic acid was 2:1:3. For applications of polymer in optoelectronics, in lithium-ion battery and in electromagnetic shielding, to obtain optimized value of conductivity has great significance for us.

Abstract:
It was of interest to search for luminescent reactions to terbium in complexes with sulfosalicylic acid derivatives and to strengthen them by studying the influence of the third components (aminopolycarboxylic acids, organic bases, and surfactants). Absorption spectra of solutions of rare earth element complexes in the wavelength range of 220-880 nm were recorded using the SF-26 spectrophotometer. To obtain the maximum luminescence of the luminescent reaction of rare earth elements in complexes with organic reagents, a number of factors that have a significant impact on the intensity of solutions of luminescent complexes have been studied. Such factors are the pH of the complexes, concentration of reagent, time of maturation complexes, the irradiation time, the order of adding the reagents and the ionic strength of the solutions. According to studies conducted, surfactants increase the luminosity of terbium ions in complexes with sulfosalicylic acid derivatives. As a surfactant, decylpyridinium chloride was used in solutions. The existence of a bright luminescent green reaction of terbium in a complex with methyl ester S- (4-bromanilide) sulfosalicylic acid was established. The optimal conditions for the complexation of terbium were selected and highly sensitive luminescent methods for determining terbium in various objects were developed. Terbium is converted into a luminescent complex compound with an organic reagent S- (4-bromanililide) sulfosalicylic acid methyl ester in the presence of a cationic surfactant decylpyridinium chloride in a ratio of 1: 2: 13, pH 7.9 ± 0.08. The resulting complex compound of terbium upon irradiation with a mercury lamp under ultraviolet light gives intense green luminescence that is stable during standing and irradiation. As a consequence, the proposed method allows to determine terbium in the oxides of rare earth elements, which are quenchers of luminescence with a sensitivity of 10-8%, bypassing the extraction stage. The sensitivity of the determination of terbium in the oxides of the remaining lanthanides is 2.4·10-10%.

Abstract:
Nanostructured samples of polyaniline (PANI) doped with different dopants (organic and inorganic) have been synthesized employing polymerization and electrodeposition. The influence of nature of dopants( organic and inorganic) and process variation on the room temperature electrical conductivity and on ammonia vapour sensing performance (response percentage and response time) has been investigated. The synthesized samples have been structurally characterized by transmission electron microscopy (TEM) and fourier transform infrared (FTIR) spectra. Regardless of type of dopants, polymerization produces nanospheres of PANI and electrodeposition leads to formation of nanorod-like structures. Among all the synthesized samples, the organic doped electrodeposited sample exhibits highest conductivity. The conductivity of the prepared samples ware measured as a function of time after exposure to ammonia indicating that the polymerized samples (both for organic and inorganic dopants) exhibit fastest response (least response time), while the electrodeposited samples show sluggish response. Thus response percentages of different samples are found to depend on the nanostructures which vary with the nature of dopants and process of preparation.

Aluminum substrate (99.7% Al) was pretreated by acetone degreasing and smoothed by chemical polishing, and then anodizing. In order to improve the properties of oxide film, sulfosalicylic acid (SSA) was added to sulfuric acid electrolyte . The hardness, corrosion resistance, and compactness of film were increased by using mixed acid electrolyte. The study is divided into two parts, the first part is sulfuric acid anodizing. By changing parameters such as voltage, temperature, concentration, to optimize the film charactertics. The second part, the mixed acids anodization, by adding different amounts of SSA to sulfuric acid to observe effect of SSA on film properties. The experimental results of the first part indicated that the optimal operating parameters of the sulfuric acid anodizing were 15 V, 10 wt% sulfuric acid and 15℃for the maximum microhardness 655 Hv and good corrosion resistance with Icorr = 0.573 nA/cm2. For the second part of experiment, mixed acid composed of 10 wt% sulfuric acid and 30 g/L sulfosalicylic acid (SSA) was used for anodization. Oxide films with better microhardness of 718 Hv, corrosion resistance with Icorr = 0.258 nA/cm2, and least porosity of 509 no./μm2 were prepared. After sealing in boiling water for 30 minutes, corrosion current can be lowered furthermore to Icorr = 0.124 nA/cm2. Addition of SSA can increase the growth rate of oxide film slightly. Based upon FT-IR and EDX analytical results, oxide film containing carbon, sulfur, oxygen, aluminum elements as well as sulfur oxygen bonding. The oxide film is amorphous phase as revealed by XRD patterns.

This study was carried out by means of the method of two-step anodic treatment in the sulfuric acid solution with the addition of 5-sulfosalicylic acid and then electrolytic coloring in cupric sulfate solution，it is expected that by adding 5-sulfosalicylic acid and technique of two-step anodic treatment, a dense and regular oxidizing film on aluminum can be obtained and that the optimum operating conditions for obtaining a blackest film are found out. It is found that at the coloring after the anodic treatment by adding 5-ssa, the thickness of the anodized colored film would become thinner than that without the addition，but it would become thicker after two-step anodic treatment by adding 5-ssa. And，the hardness of anodic film from the addition of 5-ssa is larger than that without the addition, but it would become lower after two-step anodic treatment by adding 5-ssa. From SEM、 AFM and corrosion test of the anodic film after two-step anodic treatment by adding 5-ssa,it found out that the anodic film is more regular, smoother and denser, so it has the lowest △E after the coloring. It proves that more cupric ions deposit in the anodic film after two-step anodic treatment by adding 5-ssa. At the anodic current density of 2 A/dm2 and the duration time of 20 minutes after two-step anodic treatment by adding 5-ssa, the best operating conditions of electrolytic coloring are：alternating current voltage：30V, and electrolytic coloring time：40 minutes, hence, the lowest △E value is 7.41. The average reflectivity, gloss, film thickness, hardness and corrosion rate are respectively 4.50%、8.6、10.2μm、591Hv and 3.1875E-9 Amp/cm2.

In the research, the effects of the addition of 5-sulfosalicylic acid in the sulfuric acid solution on the physical properties of the anodic film and the colored film are investigated, with the hope that by adding 5-sulfosalicylic acid, better oxidizing film on aluminum can be obtained and that it is favorable to carry out the best operating conditions for the black electrolytic coloring are searched. From the experimental results, it is found that at the coloring after the anodic treatment by adding 5-sulfosalicylic acid, the thickness of the anodic film would become thinner than the thickness without the addition and that the hardness would become larger than the hardness without the addition. It is also known from the cross-sectional and SEM of the anodic film obtained by adding 5-sulfosalicylic acid that the barrier layer is more regular and denser and that the pores of the porous layer are smaller, showing that the whole anodic film is denser. Besides, the corrosion test and the film dissolution test prove that the addition of 5-sulfosalicylic acid can effectively enhances the anticorrosive property of the anodic film and thus improves the characteristics of the black film after coloring. At the current density of the anodic treatment of 1 A/dm2, and 20 minutes after the anodic treatment by adding 5-sulfosalicylic acid, the best operating conditions of electrolytic coloring are：alternating current voltage：30V, and electrolytic coloring time：40 minutes, hence, the lowest △E value, reflectivity, gloss, corrosion rate and the better hardness can be obtained. Those values are respectively 9.18, 5.08%, 6.4, 4.9576E-10 g/m2-h and 639Hv, accordingly, the characteristics of the black colored film are greatly improved.
