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.
