  • Application of the laccase, produced on coconut flesh by        class="a-plus-plus">Pleurotus florida for dye
           decolorization
    • Abstract: Abstract We investigated the ability of Pleurotus florida to produce laccase on coconut flesh as a solid substrate fermentation. The decolorization of two structurally different dyes such as azo (Reactive Blue 198) and triphenylmethane dye (Malachite Green) were analysed. The decolorization of Reactive blue 198 and Malachite Green at 8 hrs was 93% and 63% respectiely. The untreated and treated dye was characterized by UV-Vis spectral and fourier transform infrared (FTIR) Spectroscopy scan. FTIR analysis pointed out the involvement of alkene (C=C) and carboxylic (C-O) groups in the decolorization process. The toxicity with respect to Allium cepa root inhibition was measured to demonstrate the potential of laccase in the detoxication and bioremediation process.

  • Electrocoagulation purification of water of Cr       class="a-plus-plus">6+ compounds
    • Abstract: Abstract The process of the electrocoagulation purification of water containing chromium, depending on pH, Cr6+ concentration, ions of metal impurities and ratios Fe2+ : Cr6+ have been investigated. We have found the upper boundary of chromium concentrations (150 mg/dm3) whereby its residual content in water does not exceed MAC for the discharge to the complex of facilities of water disposal. It has been shown that ions of metal impurities present in the water in electrocoagulation are removed together with chromium ions.

  • Raising the efficiency of water treatment by means of activated carbons
           with improved sorption characteristics
    • Abstract: Abstract Substantiated is the possibility of obtaining new carbon sorbents from anthracite coals of the Donetsk deposit (Ukraine). It is shown that their adsorption ability depends on the physiochemical composition of the initial feedstock and method of treatment. The article emphasized the possibility of obtaining a sorbent having a rational structure of a porous space by way of its multistage activation. The use of such sorbents makes it possible to decrease the specific consumption of activated carbon for water purification in filtering surface waters of the Dnieper River and biologically treated wastewaters of the city of Kiev.

  • Polyacrylamide derivatives as reagents for purification of waters of U(VI)
           and Cr(VI)
    • Abstract: Abstract The paper has investigated the impact of water-soluble macromolecular polyelectrolytes on the ultra- and nanofiltration process of purification of waters polluted by U(VI) and Cr(VI). Derivatives of polyacrylamide—cationic and anionic Praestols were used as such compounds. The relationship between the degree of extraction of U(VI) and Cr(VI) and the pH and concentration of Praestols was found. It has been shown that when using the latter the maximum retention coefficient of U(VI) both by ultra- and nanofiltration membranes constituted 0.999; the maximum retention coefficient of Cr(VI) by the ultrafiltration membrane—0.65

  • Selective photometric determination of nickel, cobal, and zinc in drinking
           and natural waters using 1-(2-pyridylazo)-2-naphthol and surfactants (SAS)
           
    • Abstract: Abstract Selective techniques have been developed for determination of nickel, cobalt, and zinc with 1-(2-pyridylazo)-2-napthol in waters with a lower boundary of determinable concentrations 0.01–0.02 mg/dm3. Reactions took place in micellar solutions of nonionic SAS. Selectivity of determination has been achieved thanks to the use of masking substances and a special procedure of mixing components. Iron does not hinder determination at the concentration < 5 mg/dm3.

  • Acute toxicity test using cyanide on        class="a-plus-plus">Daphnia magna by flow-through
           system
    • Abstract: Abstract This study describes the acute toxicity of sodium cyanide on the crustacean Daphnia magna (Cladocera). A new flow-through system was innovated in which the microorganism continuously exposure to the toxicity of sodium cyanide during the test. We used twelve different concentration of sodium cyanide from low values (0 mg CN/L) to high values (1 mg CN/L) on bioassay test. D. magna were exposed to the concentrations for 24, 48, 72 and 96 h at 20–25°C. We controlled the three important parameters such as temperature, pH and DO to meet the standard requirements. The LC50 values for 24, 48, 72 and 96 h (95% confidence limits in parentheses) were estimated statistically by the probit methods and were 0.171 (0.163–0.179), 0.12 (0.112–0.128), 0.07 (0.062–0.078) and 0.019 (0.011–0.027) mg/L respectively. Finally, we proposed two new values for SAR (safe application rate) and SAFE Coefficients.

  • Systematic features in the study of humic substances in natural surface
           waters
    • Abstract: Abstract The article has considered systematic approaches to the investigation of humus substances of natural surface water. It has been shown that the use of chromatographic methods for extraction humic matter from water and investigation of their molecular-weight distribution is accompanied by losses of these compounds owing to phenomena of irreversible adsorption. The comparative assessment of the methods of determining concentration of humus mater, in particular, spectrophotometry and fluorescent spectroscopy as well as methods based on the results of determination of water color and reaction of azo-combination using diazotized 4-nitroaniline has been made.

  • Monitoring of micromycetes in tap water of the city of Kiev
    • Abstract: Abstract Monitoring of tap water samples in different administrative districts of Kiev was carried out. The impact of lifetime of the water-distribution network on the amount and specific composition of micromycetes in selected samples of the water was investigated. The paper has established the presence in the water of the genera Candida, Penicillium, Cladosporium, Fusarium, and Aspergillus. The mean amount of micromycetes varies in the range from 8 to 18 CFU/100 cm3, which is an indication of the necessity to develop regulatory documents on mycological control of water and technologies for the removal from it of micromycetes.

  • The use of the DLVO theory for the study of boundary water layers near the
           surface of layer silicates
    • Abstract: Abstract For layer silicates with a clear-cut expressed laminated shape of particles we have proposed the method of measuring long-range forces, between the particles, based on swelling kinetics with a controlled load. Using the structure of structurally perfect kaolinite and a specially developed device for measuring swelling forces as an example we have demonstrated the efficiency of this method, which gives comparable results with other classical methods used in the DLVO theory.

  • The environmental impact of crude oil formation water: A multivariate
           approach
    • Abstract: Abstract Water bodies receiving effluents from gas flow stations were sampled for ten months (March to December). Fifteen physicochemical parameters were monitored at six locations. Results obtained were analyzed unsing principal component analysis and cluster analysis. Five principal componets accounting for 72.43% of total variance were isolated. The first principal component was a measure of sea water intrusion, the second componet was a measure of total solids, the third component was a measure of organic pollution while the fourth and fifth principal component depicted the impact of effluent discharges. Effluents from gas flow stations were not the major causes of pollution of water resources in the locations of study. Cluster analysis showed no significant variation in the physicochemical characteristics of water samples based on location. Physicochemical parameters exhibited a seasonal pattern as a result of dilution by rainfall, reduced rate of evaporation in rainy season and dissolution of gaseous products of gas flaring in rain. Metals had no significant effect on the quality of water sampled from the six locations during the period of monitoring.

  • Wastewater purification of biogenic elements
    • Abstract: Abstract The retention capacity of the ESPA-1 membrane for nitrates, nitrites, ammonium, and phosphates has been investigated. Its application was shown to be most effective for the removal of phosphates. In this case the membrane retention capacity amounts to ∼99.8%. Nitrates are removed on conditions of up to the 90% permeate conversion in case of their initial concentration of 400 mg/dm3 and up to the 70% conversion in the interval of initial concentrations of 400–700 mg/dm3. In the case of the initial concentration of ammonium ions equal to 300 mg/dm3 and 400 mg/dm3 their removal is possible up to the 70% and 60% permeate conversions, respectively. In relation to nitrites this membrane shows a low retention capacity; however the preliminary oxidation of the latter to nitrates makes it possible to ensure their sufficiently effective removal.

  • The change in activated sludge surface properties after heavy metals
           leaching
    • Abstract: Abstract The change in colloid-chemical properties of natural sludge sol formed as a result of biological treatment of domestic wastewater in the process of heavy metals leaching induced by metabolizing heterotrophic (acidogenic and alkaligenic) chemotrophic biocoenosis was investigated. It was found that bioleaching of heavy metals involving heterotrophs results in hydrophobization of sludge colloids and reduces its negative charge. Heavy metals leaching also results in destabilization of sludge sol, maximum in biological processes. Exopolysaccharides significantly stabilizing sludge sol have a little effect on its stability after heavy metals have been leached.
