Kravchenko A. Combined processes of formation of hydrogen polyoxides and recuperation of impurities from liquid media in nonequilibrium low temperature plasma.

The thesis is devoted to creation of scientific basis for the technology of combined formation of hydrogen polyoxides and recuperation of impurities from liquid media in nonequilibrium low temperature plasma that performed in the thin layer on liquid/plasma interface.Thermodynamic analysis of processes, which led to formation of hydrogen polyoxides, was performed. It was proposed the kinetic model of hydrogen peroxide formation that consists of two consecutive stages of first order reaction. It was calculated kinetic parameters for the process of hydrogen polyoxides formation: kostant rates of the stages k1 and k2; concentration of initial reagent; time and maximum concentration of intermediate product HO2o. It was determined that limiting stage of the process is formation of HO2o radicals. It was established the main regularities of recuperation processes for inorganic compounds and radionuclides from liquid media in nonequillibrium low temperature plasma. Unwanted impurities are transformed to insoluble compound then they are aggregated and removed by filtration. It was shown that process of treatment of surfactant solutions consists of combined reactions of hydrogen polyoxide synthesis and oxidizing destruction of organic compounds. The macrokinetic model was proposed for the gas-liquid reactor using nonequilibrium low temperature plasma. The instrument-technologycal design for realization of combined processes of hydrogen polyoxide formation and recuperation of inorganic compounds and radionuclides, oxidizing destruction of organic compounds and biological pollutants was proposed on the basis of theoretical and experimental research. Keywords:nonequilibrium low temperature plasma, combined processes, hydrogen polyoxides, recuperation of inorganic compounds and radionuclides, oxidizing destruction of organic compounds.
