  • Impact of montmorillonate on the process of purification of waters
           containing uranium by ultra- and nanofiltration
    • Abstract: Abstract The article has investigated the impact of montmorillonite (natural and modified) for purification of waters containing uranium by ultraand nanofiltration. It has been shown that maximally possible uranium retention coefficient by a nanofiltration membrane was obtained when a modifier with the molecular weight 2 kDa was used. Whereas for an ultrafiltration membrane a high index of purification is achieved when using a modifier with the molecular weight 10 kDa.

  • Electrochemical methods of hydrogen peroxide control in aqueous media
           under dynamic conditions
    • Abstract: Abstract Concentrations of hydrogen peroxide in dynamic (flowing) electrolytes and suspension systems have been determined using the methods of potentiometric redox-titration and cyclic voltammetry. The quantitative determination of H2O2 up to concentration ≈ 10–6 M was shown to be possible by using microelectrodes polarized in the convective diffusion mode, while employing the voltammetry, and using the mathematical processing of results of micropotentiometric titration. The effect of hydrophobicity of the reactor surface on the resulting concentration of H2O2 has been detected that should be taken into account during the microanalysis.

  • The use of ferrocyanide Zn/Al-hydrotalcite for the sorptive concentration
           and radiometric determination of 137 Cs in waters
    • Abstract: Abstract A sorbent based on Zn/Al-hydrotalcite intercalated by hexacyanoferrate (II)-ions is proposed for 137Cs concentration and its further radiometric determination in natural waters. Parameters for the optimal sorptive extraction of radiocesium from waters under static conditions and direct radiometric measurements have been determined. The use of ferrocyanide sorbent is shown to provide a good potential in analytical schemes of 137Cs concentration from waters with high salt background.

    • Abstract: Abstract The paper has investigated the process of measuring power illumination for vacuum ultraviolet radiation by means of the solution of potassium iodide as a photochemical actinometer. We have investigated the formation of triiodide–ion when radiated the solution of light with wavelength 185 nm. It has been shown that obtaining hydroxyl radicals OH– at this wavelength is determined by the formation of I 3 – . The quantum yield of the process constitutes 0.165. Measuring the concentration of the obtained I 3 – we determined power illumination of a quartz lamp DRB-20 (wavelength 185 nm), which constitutes 49.2 × 10–9 E/s.

  • Synthetic polymers and their blends for removing lead from aqueous
    • Abstract: Abstract The article has investigated main commodity synthetic polymers (polyethylene terephthalate(PETP), polyethylene (PE) and polystyrene (PS) and their blends designed for adsorption of lead ions from wastewaters. Blends were prepared by extrusion from the melt at PS concentration from 5 to 20 fraction of total mass, %. The time of attaining equilibrium at adsorption of lead ions on the polymer surface has been found. The obtained data indicate that polymers in question were more efficient compared with others, which investigated for assessing their adsorption ability with respect to lead ions. Results of equilibrium isothermal adsorption of lead ions on the mixed PETP/PS system point out that at an increase of percent content of PS in the blend a substantial increase of adsorbed lead is achieved per unit weight of polymer adsorbent. This correlates with the type and dimensions of interface morphology of blends.

  • Impact of different frequencies in the entrapment of bacterial pathogens
           from drinking water using dielectrophoretic phenomena
    • Abstract: Abstract The article has investigated the removal of water borne pathogens using dielectrophoresis (DEP) filter which is energized by varying the frequency of the applied potential from 10 kHz to 2 MHz with different voltage levels of 5; 10; 15 and 20 V. Separate experiments are conducted in artificially contaminated water samples with Escherichia coli, Staphylococcus aureus and Vibrio cholerae up to 2 h. The impact of signal frequency and voltages on DEP based water treatment system has been analyzed statistically. Results have demonstrated that an AC signal of 20 V with frequency range of 500 kHz to 2 MHz is suitable to remove the tested bacterial population and the rate of removal of E. coli is the highest with a dielectrophoretic filtration efficiency of 77.1%.

  • The use of fuchsin basic for determination of bromide–ions in waters
           by the method of reflection colorimetry
    • Abstract: Abstract Photometric technique has been developed for determination of bromide ions in waters; the technique is based on oxidation in an aqueous solution of bromide to bromine by chloramine T, concentration of bromine–derivative fuchsine basic on membrane filters and measurement of lightness of obtained colored concentrates in a thin layer by means of reflection colorimetry. The detection limit of bromide–ions constitutes 10 μg/dm3, the linearity of the calibration curve ranges from 10 to 1000 μg/dm3. The excess of chloramines T does not interfere with determination, which simplifies and reduces the analysis. The proposed technique is more sensitive, fast and simple in execution than existing standard techniques. It makes it possible to control the content of bromide–ions in waters both at the level and lower than MAC and may be used in field conditions at the site of sampling

  • Impact of characteristic of activated carbons on the efficiency of removal
           from water of pharmaceutical preparations of various chemical nature
    • Abstract: Abstract The article has investigated regularities of adsorption of sulfanilamide, sulfathiazole, levamizole and procaine on activated carbons KAU and Filtrasorb F400. Within the interval of concentrations 0.1–1 mol/dm3 the series of adsorption affinity of substances under research on both carbons coincide. Adsorption values decrease in the following sequence: sulfanilamide > sulfathiazole > procaine > levamizole. It has been shown that for the removal from water of the mixture of pharmaceutical preparations with different physicochemical properties it is expedient that the combination of mainly microporous carbon sorbents have different surface chemistry.

    • 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.
