A review, with 29 refs., on the anodic oxidn. of orgs. in industrial wastewaters treatment. Direct electrochem. processes catalyzed by the O transfer reaction are discussed for several anode materials. Ti/SnO2 is particularly efficient for cold combustion of arom. pollutants. Processes involving the electrochem. generation of oxidants (O3, H2O2), or the electrochem. regeneration of metallic redox couples (Fenton's reagent) are discussed. [on SciFinder (R)]
