Abstract

The conditions of indirect destructive oxidation of phenol by hydrogen peroxide generated electrochemically from oxygen in gas diffusion electrode in alkaline medium in an electrolyzer without cation-exchange membrane are considered. The dependence of phenol oxidation rate and efficiency on current density, concentration and composition of electrolyte is investigated. The major routes of the activation of phenol oxidation and conditions for utilization of organic components from aqueous solutions are determined.
