Electrochemical Treatment of Industrial Organic Effluents

Abstract

The anodic oxidation of organics is a potentially powerful technique of controlling pollutants in industrial waste waters. Based on a fundamental analysis, this paper summarizes recent results in this field. Direct electrochemical processes catalyzed by the oxygen-transfer reaction are discussed for several anode materials. Ti/SnO₂ is particularly efficient for cold combustion of aromatic pollutants. Potential candidate processes involving the electrochemical generation of oxidizer reactants (O₃, H₂O₂), or the electrochemical regeneration of metallic redox couples are discussed.
