Faradaic Processes at the Interaction of Low-Temperature Plasma with Water and Aqueous Solutions

Resumo

The paper considers the mechanism of reactions that lead to a change in the physicochemical properties of water in the case of its electrochemical activation with non-equilibrium plasma. The uniqueness of the method of the low-temperature plasma electrolysis (LTPE) consists in the fact that one electrode is placed in the liquid phase while the other is placed at some distance from the surface of the liquid, which offers new possibilities for the electrochemical method. It is shown that in the LTPE treatment of water, some destructive changes occur, which can result in the formation of peroxide and superoxide compounds with high oxidation properties. It is supposed that the mechanism of these processes is based on the appearance and functioning of a bipolar electrode at the liquid–gas interface.
