Seasonal variations of characteristics of organic matter in the Dnieper River water
02-Jul-2012 | N. A. Klimenko, E. A. Samsoni-Todorova, L. A. Savchina, I. N. Lavrenchuk, T. N. Zasyad’ko, Journal of Water Chemistry and Technology, 2012
The paper assessed characteristics of natural organic substances of the Dnieper River (Kiev) by seasons of the year based on determination of such parameters as total organic carbon, absorption in the ultraviolet region (UV254), specific absorption (SUVA), and color. It has been shown that in ...
Theoretical aspects of natural and drinking water biotesting
05-May-2012 | V. V. Goncharuk, V. F. Kovalenko, Journal of Water Chemistry and Technology, 2012
The scientific and theoretical framework for the natural and drinking water biotesting is provided. The structure of biotesting procedure in general and methodological approaches to the evaluation of low polluted water quality in particular was studied. The definitions for biotesting process are ...
Sorption-desorption processes in the system of U(VI)-layered double hydroxide intercalated with EDTA
05-May-2012 | V. V. Goncharuk, G. N. Pshinko, L. N. Puzyrnaya, Journal of Water Chemistry and Technology, 2012
We have investigated sorption-desorption processes in the U(VI)-layered double hydroxide intercalated with EDTA at pH 7.5 characteristic of natural ad waste waters. The paper provided U(VI) sorption kinetics and its interpretation in the form of the model of pseudosecond order ensuring the ...
The effect of carbon dioxide on the viability of bacteria of Bacillus and Diplococcus genera
05-May-2012 | I. Z. Koval, V. N. Kislenko, V. L. Starchevskii, L. I. Shevchuk, Journal of Water Chemistry and Technology, 2012
The effect of the volume of carbon dioxide gas released from aqueous solution on the reduction of the number of vegetative microorganisms per unit volume of the system has been investigated. A linear relationship between the number of vegetative microorganisms and the volume of released carbon ...
Filtration of suspensions at the descending rate at linear kinetics of mass exchange
05-May-2012 | V. L. Polyakov, Journal of Water Chemistry and Technology, 2012
We have presented an effective approximated solution of the problem of filtration of a suspension at the set pressure heads at the boundaries of the medium and linear kinetics of mass transfer. We have developed the procedure of determining the time of a filtration cycle based on two criteria ...
The system of the efficient monitoring of air quality in maritime cities and health resort areas: Pollution of the nearwater layer of the atmosphere with sea aerosols
05-May-2012 | V. V. Goncharuk, V. B. Lapshin, M. A. Chichaeva, A. O. Samsoni-Todorov, V. V. Taranov, I. S. Matveeva, G. N. Chikvil ..., Journal of Water Chemistry and Technology, 2012
The system of the efficient monitoring of air quality for maritime cities and health resorts has been set up. A basis for the prototype of such a system is establishment of functional links between the concentration of toxic substances in the air and the disperse composition of sea aerosol and ...
Inactivation of Candida albicans in the photo-fenton system
05-May-2012 | N. M. Soboleva, M. N. Saprykina, V. N. Kosinova, A. A. Nosonovich, V. V. Goncharuk, Journal of Water Chemistry and Technology, 2012
The paper has investigated photocatalytic decontamination of the culture of micromycetes Candida albicans in water media depending on the radiation dose (UV-A range), the pH of the medium, the concentration of H2O2, ions of iron (II), (III), and phosphate ions. We proposed the interpretation of ...
Removal of phenols from aqueous solutions using tyrosinase immobilized on polymer carriers and inorganic coagulants
05-May-2012 | Yu. A. Shesterenko, O. V. Sevast’yanov, I. I. Romanovskaya, Journal of Water Chemistry and Technology, 2012
The methods for the removal of phenolic compounds (0.5–10 mmol/dm3) from aqueous solutions and selective separation of its mixtures based on the oxidation of phenols using tyrosinase isolated from Agaricus bisporus and immobilized on polymer carriers as well as the removal of bioconversion ...
Seasonal fluctuations in the content of different forms of organic carbon and their changes in water treatment processes
05-May-2012 | N. A. Klimenko, E. A. Samsoni-Todorova, L. A. Savchina, T. P. Chekhovskaya, I. N. Lavrenchuk, T. N. Zasyad’ko, Journal of Water Chemistry and Technology, 2012
We have assessed the content of different forms of organic carbon (total, bioaccessible, and assimilated) in the water of the Dnieper river in the area of the water intake of the Dnieper water station and in the water after all treatment stages used. The article has investigated seasonal changes ...
Mathematical simulation of the process of biofiltration of aromatic compound solutions through a dense layer of activated carbon during the water treatment
06-Mar-2012 | A. V. Sinel’nikova, N. A. Klimenko, S. K. Smolin, L. V. Nevinnaya, O. V. Zabneva, A. A. Sinel’nikov, O. G. Shvidenko, Journal of Water Chemistry and Technology, 2012
Using the biofiltration of o-nitrophenol and anthranilic acid solutions as an example, it has been shown that the computer-aided simulation can be applied for calculating the water treatment efficiency by the orthogonal collocation and finite difference methods using the Crank-Nicholson scheme. ...
