  • Spectrophotometric determination of trace nitrite with a novel
           self-coupling diazotizing reagent: J-Acid
    • Abstract: Abstract A simple and sensitive method for the spectrophotometric determination of nitrite was described and optimum reaction conditions along with other important analytical parameters were established. In the presence of potassium bromide at 25°C, nitrite reacted with J-acid in hydrochloric acid producing diazonium salt and then coupled with excess J-acid in the sodium carbonate solution yielding red colored azo compounds. At wavelength of 500 nm, Beer’s law was obeyed over the concentration range of 0.02–0.60 mg·L–1. The molar absorptivity was 3.92 × 104 L·mol–1·cm–1. This method was easily applied to the determination of trace nitrite in environmental water with recoveries of 98.7–101.2%.

  • Change of the composition parafinnaphthenic hydrocarbon fraction in
           biological purification of water of oil
    • Abstract: Abstract Investigated are changes in the composition of paraffin-naphthenic hydrocarbons (PNH) in purifying water by the preparation Ekolan-M of crude oil. The main components of PNH are n-alkanes C9–C30 and iso-alkanes C8–C17. The absence in the purified water of iso-alkanes C9 and the presence in it of a small amount of n-alkanes C22–C26, whose concentration decreased compared with the initial one by 150–234 times is an evidence of nearly complete utilization by microorganism of the preparation of these fractions of hydrocarbons.

  • Chromatographic determination of pesticide 2,4-D in water bodies
    • Abstract: Abstract New silica-based adsorbent with covalently immobilized groups of triton X-100 has been proposed for extraction and concentration of 2,4-dichlorophenoxyacetic acid (2,4-D) from water bodies. The recovery of this pesticide into adsorbent phase occurs in the form of its ionic associate with cationic surfactants (CSAS). It was shown that the application of cetyltrimethylammonium bromide made it possible to achieve the pesticide extraction ratio as high as 94%. Elution with acetonitrile allows us to achieve a 50-fold absolute concentration of 2,4-D making it possible to perform its determination by the high performance liquid chromatography method with ultraviolet detection, where the detection level is 0.07 mg/dm3 and the linearity range is from 0.09 to 0.20 mg/dm3.

  • The study of properties and catalytic activity of titanium dioxide doped
           with sulphure
    • Abstract: Abstract Comparison was made by activity of TiO2 doped with sulphur (S-TiO2) and pure TiO2, synthesized by the sol-gel method, with TiO2 Degussa P-25 in course of photocatalytic oxidation by oxygen of the air of aqueous solutions of fulvic acids, humic and picric acids at two modes of radiation by a SVD-120 lamp (λ > 200 or λ > 320 nm). It is shown that at oxidation of fulvic acids and humic acid the activity of S-TiO2 is substantially higher than the activity of pure TiO2 under both modes of radiation, however, under conditions of the experiment the given samples were less effective at oxidation by picric acid.

  • Leaching heavy metal from deposits of heavy metals with bacteria oxidizing
           elemental sulphur
    • Abstract: Abstract Experiments were carried out on bacterial leaching heavy metals from aerobically stabilize excessive activated silt of Bortnichi Aeration Station of Kiev when adding elementary sulphur as a stimulant of the activity of acidophilic thiobacilli. It has been shown that a decrease of silt pH in the course of the process is a decisive factor of efficiency of leaching heavy metals.

  • Indirect spectrophotometric determination of sulphides with
           N,N-dietylaniline
    • Abstract: Abstract Proposed is the technique of spectrophotometric determination of sulfide in the range 0.05–1.50 mg/dm3 based on oxidation of it in the sulfate medium by the known excess of bromate followed by subsequent oxidation of N,N-diethylaniline in the presence of the excess of bromide and photometering at 226 nm of 4-bromo-N,N-dietylaniline being formed. The sulfide detection limit constitutes 0.03 mg/dm3. Metrological characteristics of the technique were checked by way of determination of sulfide in waters in ballneotherapy (mud, silt, etc.).

  • Bioadsorbent Hura Crepitans for the removal of phenol from solution
    • Abstract: Abstract The use of Hura crepitans (sandbox tree) seed as a biomass adsorbent was studied for the removal of phenol from aqueous solutions before extraction (HC) and after extraction (EHC) with hexane and methanol. The surface chemistry of HC and EHC was characterized by using the Boehm titration and pH drift while the removal of phenol from solution was monitored by using high performance liquid chromatography (HPLC). Decrease in the pH of solutions led to a significant increase in the adsorption capacity of HC and EHC. The linear regression of the experimental data showed that the Freundlich model fitted well with the values of adsorption capacity equal to 121 mmol/g for HC and 85 mmol/g for EHC, and the pseudo-second order kinetic model best described the adsorption process for HC and EHC. The experimental data indicated that the seed of Hura crepitans could be effectively used as an adsorbent for the removal of phenol from aqueous solutions.

  • Simultaneous determination of inorganic anions in bottled drinking water
           by the ion chromatography method
    • Abstract: Abstract Simultaneous analysis of seven inorganic anions (fluoride, chloride, nitrite, bromide, nitrate, phosphate and sulfate-ions) was carried out in two sets of 10 brands of mineral bottled waters (Iran) using ion chromatography (IC). Waters were sampled in autumn and winter of 2010. The obtained concentrations compared with the values on the labels. It was established that concentrations of the specified ions in tested waters were within the acceptable levels of the World Health Organization (WHO) and the United States Environmental Protection Agency (USEPA). Comparison of label values with our experiments showed that 11 label values had meaningful difference from the corresponding test values. The analysis of variance (ANOVA) revealed that sampling in autumn and winter periods did not influence the content of ions in water.

  • Assessment of sorption of 137 Cs and 90 Cr in model soil-water systems
    • Abstract: Abstract The paper has investigated sorption of 137Cs and 90Sr on natural clayey minerals—montmorrilonite of the Cherkassy and kaolinite of Hlukhovets deposits and their modified forms by means of precipitation of hydroxides of Fe(III) an humic acids with fraction of total mass 5%. It has been found that both for natural minerals and for their modified forms the most effective sorption of radionuclides from aqueous solutions is observed in a broad area of the pH characteristic of natural soil media. An increase of the sorption value of radionuclides occurs in the series: M < M-GK < M-Fe. A similar relationship is observed also for kaolinite samples. We have determined the impact on the sorption of 137Cs and 90Sr of cations-macrocomponents—Na+ and Ca2+ characteristic of natural water media.

  • Phase transition in waters with different content of deuterium
    • Abstract: Abstract According to kinetics of temperature changes and laser light scattering on density heterogeneities we investigated waters with different content of deuterium in the area of their phase transition. It has been found out that protium/deuterium ratio substantially affects the process of phase transition water-ice-water in non-equilibrium conditions (the rate of temperature changes—2°C/min): temperature of light water ice melting (D/H = 4.2 ppm) constitutes 1.1 ± 0.3°C against 0.0 ± 0.3°C for high ohmic deionized water (D/H = 140 ppm) and 3.8 ± 0.3°C—for heavy one. Determined are special features of changes in phase state of water on the basis of concepts about water as a colloid system containing deuterium and stabilized gigantic heterophase clusters.

  • Interaction of water molecules with hydrophilic and hydrophobic surfaces
           of colloid particles
    • Abstract: Abstract The hydrophobicity of talc basal surface and the hydrophilicity of silica gel surface have been considered. Ab initio calculations of energy and geometry of microclusters formed by water molecules on active centers of ideal basal surface of talc and silica gel surface were carried out. It was shown that the typical property of hydrophobic surface is the adsorption of single molecules on weak centers (oxygen atoms of siloxane group) of talc surface that next serve as secondary centers of adsorption of water molecules. At the same time the water adsorption on strong active centers (vicinal pairs) of silica gel surface leads to the formation of a cluster having the structure similar to that of liquid water. Accordingly an adsorption layer near the hydrophobic surface is depleted, while a layer near the hydrophilic surface is enriched with adsorbate molecules.

  • The isotope effect in formation of surface water clusters in heterogeneous
           systems
    • Abstract: Abstract Using the method of low-temperature 1H NMR-spectroscopy we investigated isotope effects in adsorption of water and hydrochloric acid by the surface of nanosilica A-300 and in particular dehydrated cells Saccharomyces cerevisiae. It is shown that replacement of protium by deuterium results in the growth of the amount of water bound with silica. Solutions of H(D)2O-H(D)Cl are characterized by the formation of several types of cluster structures different in concentration of acid. The ratio of intensities of signals corresponding to various types of clusters substantially depends on the isotope composition and for samples enriched with deuterium it shifts to the side of less associated forms of water.
