Electrochemical behavior of diluted aqueous electrolytes containing oxygen after superimposition of mechanical effects

We have conducted potentiometric and voltamperometric research of strongly diluted aqueous solutions of electrolytes in stationary and dynamic conditions. We have found a mechanochemical effect on the readings of a standard redox electrode in model solutions and natural waters, which is absent in degassed solutions. Cyclic voltamperometric investigations under stirring conditions demonstrated the emergence in the anodic region of a current of hydrogen peroxide formation in systems containing dissolved oxygen. Introduction into the solution of a structuring additive—a suspension of natural minerals, which did not result in the changes of the initial concentration of the electrolyte solution made it possible to substantially increase anodic current. We have received a proof of a possibility of mechanochemical formation of oxidants in natural waters.
