Abstract

Electrochemical oxidation of phenol was studied using Ti/IrO2/RuO2 anode and a carbon/polytetrafluoroethylene (C/PTFE) O2-fed cathode which generated hydrogen peroxide (H2O2) by the reduction of oxygen in the undivided cell and the divided cell with a cotton diaphragm. For degradation mechanism of phenol on the cathode and anode, two kinds of cells are similar. However, the basic condition of the cathodic compartment in the divided cell was prone to H2O2 changed to and HO 2 and HO·. So, the mineralization of phenol in the divided cell was better than that in the undivided cell.
