  • Evaluation of water quality control by using test organisms and their
    • Abstract: Abstract The use of biotesting for quality assessment of different waters. This method consists in determining the action of toxicants on specially selected organisms under standard conditions with registration of changes at behavioral, physiological, cellular and subcellular levels. A micronucleus test and Arneth’s formula as a biomarker were proposed for an optimal set used to determine specific structural and functional changes in the cell genome caused by toxic effects. A particular attention was paid to assessing the risk to human health of those factors and substances, the genotoxicity and cytotoxicity of which can be identified by using biomarkers of plant and animal cells.

  • Low-temperature synthesis, structure-sorption characterisics and
           photocatalytic activity of TiO 2 nanostructures
    • Abstract: Abstract The article addresses a practicable and economic low-temperature method of TiO2 synthesis, which allows us in a specific manner to influence structure-sorption characteristics and photocatalytic activity of samples not at the expense of the change of temperature of finite treatment, but rather by way of varying additions of the precipitant and modifier. This method helped obtain nanodisperse TiO2 with a developed specific area of the surface and high photocatalytic activity with respect to dyes of the anionic and cationic types. Individually obtained TiO2 samples display activity even higher than commercial products.

  • Adaptive capabilities of hydrobionts to aqueous medium with different
           physicochemical parameters
    • Abstract: Abstract The causes and physiological-biochemical mechanisms of migration of marine species of hydrobionts to fresh waters of the Dnieper River and the cascade of its reservoirs have been investigated. The possible adaptation of marine fish species and invertebrates is related to the economic human activity: regulation of river runoff, creation of a cascade of reservoirs with large water-surface area, anthropogenic pollution of natural water, and also changes of climate conditions on the Earth (global warming). It is presumed that these processes result in significant change of physicochemical indicators of aquatic medium. One can observe the rise of mineralization, increase of the number of biogenic compounds, variation of their ratio in fresh water that, in turn, allows the marine species of hydrobionts to adapt to new conditions and advance upstream.

  • Removal of humic acid from aqueous solution using MgO nanoparticles
    • Abstract: Abstract The main purpose of this work was to investigate the removal of humic acid (HA) from aqueous solutions using MgO nanoparticles as a novel adsorbent. The effect of contact time, competing anions in the aqueous solutions, for the removal of HA in batch system was studied. The nanoparticle was characterized by scanning election microscope method. Experimental results show that MgO nanoparticles can remove more than 90% of HA under optimum conditions. The results showed that the examined interfering anions influenced the HA removal. The adsorption kinetics and isotherm were also studied. The adsorption kinetics was well described by the pseudo-second-order equation, and the adsorption isotherms were better fitted by the Langmuir model.

  • Bioleaching of heavy metals from wastewater sludge by ferrous iron
           oxidizing bacteria
    • Abstract: Abstract Experiments on bacterial leaching of heavy metals from aerobically stabilized surplus activated sludge at the Bortnichi aeration plant in Kiev have been conducted with addition of FeSO4 • 7H2O as a stimulant of iron-oxidizing bacteria. The mechanism of heavy metal leaching involving the ferrous iron oxidation by bacteria with subsequent formation of Fe(OH)3 was confirmed. This process is accompanied by the reduction of pH level of wastewater sludge that results in leaching of heavy metals.

  • Phenol degradation mechanism by electrooxidation using stainless steel
    • Abstract: Abstract The pathway of phenol degradation by electrochemical oxidation was studied in an aqueous solution using AISI 304 stainless steel electrodes. The increase in pH due to the generation of NaOH in the aqueous solution was found to be critical for the proposed degradation mechanism since the deprotonation of phenol occurs at pH 10. The phenoxy anion produced as a result of deprotonation is resonance stabilized. The Fe+3 ions (Lewis catalyst) released from the stainless steel anode and the chlorine gas formed by the electrolysis of sodium chloride are found to be responsible for the chlorination of phenoxy anion ensuing the formation of 2-, 4-, 6-substituted chlorophenols. The mechanism was proposed for elucidating the possible degradation pathway of phenol under the above specified conditions.

  • 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.

  • Indirect spectrophotometric determination of sulphides with
    • 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.
