N2 - In this paper, photoelectro-synergistic catalysis oxidation of organics in the water on Ti/TiO2/PbO2 electrode was investigated. The prepared TiO2 film was investigated with Atomic force micrograph (AFM). Furthermore, the results were compared with those obtained from electrocatalysis (EC) and electro-assisted photocatalysis (PC). The method proposed employed photoelectro-synergistic catalysis (PEC), together with flow injection analysis, to determine the chemical oxygen demand (COD) values. It was shown that the method of photoelectro-synergistic catalysis had lower detection limit (15.0 mg l-1) and wider linear range (30.0-2500.0 mg l-1) than the methods of electro-assisted photocatalysis and electrocatalysis. The results obtained by the proposed method and conventional one were compared by carrying out the experiment on 20 wastewater samples and also agreed well by high correlation (R = 0.9912).
