The efficiency and the mechanism of aniline degradation by an electrochemical oxidation process using Ti/SnO₂-Sb₂O₅ as anode and graphite as cathode were studied in two aqueous electrolytes with/without Fe²⁺. The results showed that the oxidation of aniline could not take place only by the single action of H₂O₂. Anodic oxidation was accounted for the degradation of aniline in the absence of Fe²⁺, while in the presence of Fe²⁺ both electro-Fenton oxidation and anodic oxidation (dual-electrode electrochemical oxidation) could destruct aniline effectively, and in this case the former was the main mechanism. Under the conditions of cathodic potential 0.65V, pH 3.0 and 0.5mM Fe²⁺, the removal rate of COD was 77.5% after 10h treatment and a current efficiency of 97.8% for COD removal could be obtained. This work indicates that the dual-electrode electrochemical oxidation is feasible for the degradation of organic compounds by using Ti/SnO₂-Sb₂O₅ as anode as well as the reasonable electrode potential; in addition, a high current efficiency can be achieved.
