Electrochemical Treatment of Industrial Organic Effluents

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.
