Abstract

The electrochemical oxidation of p-chlorophenol on porous Ti/BDD electrode cooperated with synergistic effect of cathode dechlorination was studied. Electrochemical degradation tests of p-chlorophenol were conducted in single and double compartment electrolytic cells separately, and the results showed that the mineralization happened mainly in the anode region. The product of chloride ions produced from the cathodic reduction of 4-chlorophenol in the single cell migrated to the anode region and further generated active chlorine toward electro-catalytic oxidation. At the same time, the chloride ion produced from the cathode of the double cell was difficult to be migrated to the anode region, which led to better degradation efficiency in the single compartment electrolytic cell. Combining with high performance liquid chromatography, the intermediate products in the anode region, including benzoquinone, catechol and phenol, were determined, while the major product in the cathode region was phenol. The degradation pathway of p-chlorophenol on BDD electrode was suggested based on the detected intermediate products
