Physicochemical Activation of Distilled Water by a Jet of Microwave Plasma Argon in an Atmosphere of Water Vapor

Abstract

A method for activating water by plasma of an electrodeless torch discharge in a microwave electromagnetic field in argon in an environment of water vapor, at atmospheric pressure, to obtain a pure solution of hydrogen peroxide H₂O₂ without impurities in distilled water is proposed. It is shown that the main mechanism for the formation of atomic hydrogen H^• and hydroxyl HO^• radicals in the water decomposition is photolysis under the influence of excimer vacuum ultraviolet radiation of argon plasma. Hydrated electrons can be an additional source of radicals in liquid water when the plasma torch comes into contact with the water surface. Today plasma technologies are widely used to produce activated water containing hydrogen peroxide, to solve environmental problems, to increase productivity in agriculture, and for medical use.
