Разработана модель накопления пероксида водорода, учитывающая зависимость кинетики его распада от времени горения разряда. Экспериментально исследовано накопление Н2О2 при длительных временах воздействия разряда, а так же неравновесный перенос раствора в газовую фазу под действием ионной бомбардировки. Обработка экспериментальных данных на основе предложенной модели позволила определить времена жизни Н2О2 и показала, что роль неравновесного переноса невелика.

The accumulation of hydrogen peroxide in plasmasolution systems with an electrolyte cathode under glow discharge action in the dependence of cathode material has been studied as well as the kinetics of accumulation of Cu2+, Ni2+, Ag+ at the discharge ignition. It is shown that the Cu2+ concentration is comparable with that of Н2О2 and that the use of passing from the cathode into the solution a silver cathode results in a considerable decrease of the initial formation rate and the highest concentration of hydrogen peroxide in the plasma-solution system under study.

The influence of alcohol additions (ethanol and propanol-2) to electrolyte solution at hydrogen peroxide formation under the action of glow and gliding discharges of atmospheric pressure was under study. It was found out, that alcohol additions up to 0.1 mol/l increase Н2О2 yield essentially.

The subject of present investigation was the formation of hydrogen peroxide and ozone in electrolyte solution under the action of the diaphragm and glow discharges of atmospheric pressure. Kinetic of Н2О2 formation depending on diaphragm discharge current and cathode material was under study. Hydrogen peroxide was found out to be the only stable secondary product, formed in solution under the action of both diaphragm and glow discharges.

The accumulation of hydrogen peroxide in inert electrolyte solution (Na2SO4) under the action of glow discharge of atmospheric pressure was under study. Amounts of OH-radicals and hydrogen peroxide, transferred from solution into gas phase were estimated. Н2О2 yield was shown to be decreased with the increase of interelectrode distance due to the growth of hydrogen peroxide transfer into gas phase under the action of ion bombardment of solution surface.

In the present work the change of acidicy and electroconductivity of electrolyte solutions under the action of glow discharge of atmospheric pressure were under study. The changes in solution properties under discharge treatment were found out to be attributed to the formation of nitrogen oxides in plasma zone with their following solution in liquid phase. The rate of atmospheric nitrogen bonding in plasma zone above the solution surface was estimated.

In the present work a study of oxidation of K4[Fe(CN)6] to K3[Fe(CN)6 under the treatment of positive glow discharge of atmospheric pressure was carried out. The dependence of the K3[Fe(CN)]6 oxidation kinetics on its initial concentration and on the discharge current was studied as well as the influence of KCl -radicals acceptors. Initial rates of K3[Fe(CN)]6 oxidation and yield-to-current values were obtained for different discharge currents. Oxidation reactions, initiated by OH* addition as the catalyst of hydrogen peroxide decomposition and that of several alcohols as OH* zone of discharge only, and their rates would be limited by the transport of initial substances into the area of cathode spot and of interaction products out of it. -radicals, were shown to take place in primary active

The subject of present study was the reduction of KMnO4 in aqueous solutions under the action of glow discharge of atmospheric pressure. The influence of the discharge current and the initial solution pH on the reduction process rate was investigated. The course of post-effect was studied at various conditions of discharge treatment. The post-effect was shown to be due to the accumulating of hydrogen peroxide and nitrogen acid in the solution, while the later acts as the inhibitor of the reduction.

The passage of the current under industrial frequency (the voltage 12 kV) trough dielectrical tubes filled with electrolyte solutions cause the formation of plasma structures, involving up to tree simultaneously existing plasmoids. Their appearance may be as cylinder with the length up to four diameters of the tube, disk or ring. This structures move along tubes, as a rule, in the direction of the solution movement, and their lifetime is up to 0.2 s. The discharge current in the period of plasmoid existence is the sequences of pulses with the mentioned above duration, modulated with the frequency of 50 Hz. This type of plasma-solution system is characterized by high efficiency of modification action at highmolecular compounds.
