Degradation of O-Chlorophenol in a Micro-Electrolysis Contact Oxidation System


Article Preview

The characteristic and mechanism of o-chlorophenol degradation in a micro-electrolysis contact oxidation system has been investigated.The degradation rate of o-chlorophenol is higher in acid solution than that of in neutral or alkaline solution.Addition of activated carbon can make the degradation of o-chlorophenol easier by the surface contact catalysis.The dissolved oxygen in solution can take part in the electrode reaction and intensify the degradation of o-chlorophenol. Most intermediate products are 1,2-Benzenediol, glycerol, oxalic acid and acetic acid. By the analysis of intermediates for degraded o-chlorophenol, the possible degradation pathway of o-chlorophenol has been proposed.
