Effect of Ion Exchange Membrane on Pentachlorophenol Degradation by Biofilm-electrode Method

doi:10.7503/cjcu20130421

Abstract

Abstract:

Effect of ion exchange membrane on pentachlorophenol degradation by biofilm-electrode method was studied. It was found that the use of anion exchange membrane had the better results for the PCP conversion and the intermediaters removal compared to the use of cation exchange membrane. In an electrolytic cell consisted of Ti/PbO₂ anode, biofilm-electrode cathode and the anion exchange membrane diaphragm, the biofilm electrode method has much better results for the PCP degradation rate and the intermediate removal compared to the biological and electrochemical methods. The PCP degradation rate and the chemical oxygen demand(COD) removal rate can both reach 96%(mass fraction) in a treatment period of 24 h.
