Abstract

Electrochemical advanced oxidation has been receiving a growing attention in wastewater treatment because of its advantages of environmental friendliness, less secondary pollution and ease-to-handle operation. Magnéli-phase titanium oxides (TinO2n-1, n=4~10) represent the most promising electrode materials, due to its high conductivity, strong corrosion resistance and high oxygen evolution potential. In this study, we fabricated a Magnéli-phase Ti4O7 conductive membrane for electrochemical oxidation of 4-chlorophenol pollutant. The results demonstrated that the Ti4O7 electrode has lower charge transfer resistance and solution diffusion resistance compared with carbon cloth. Based on the optimization of key operating parameters, the optimum electrolyte concentration, current density and membrane flux conditions are determined to be 0.03 mol/L, 5 mA/cm2 and 0.023 m3/(m2·s), respectively. The overall removal of 4-chlorophenol could reach the level higher than 95% under these conditions.
