摘　　要：在微电解接触氧化系统中,研究了2-氯酚的降解特性和机理。在酸性溶液中,2-氯酚的降解效率比其在中性和碱性溶液的高。向其中加入活性炭,由于表面催化的作用使得2-氯酚更易降解。溶液中的溶解氧参与电极反应并促进2-氯酚的降解。降解产物有1,2-苯二酚、丙三醇、草酸和乙酸。通过对中间产物的分析,提出了2-氯酚可能的降解途径。The characteristic and mechanism of 2-chlorophenol degradation in a micro-electrolysis contact oxidation system were investigated. The degradation efficiency of 2-chlorophenol was higher in acidic solution than that of in neutral or alkaline solution. Addition of activated carbon could make 2-chlorophenol easier be degraded by the surface contact catalysis. The dissolved oxygen in solution could take part in the electrode reaction and intensify the degradation of 2-chlorophenoL Most intermediate products contained 1,2-benzenediol,glycerol,oxalic acid and acetic acid. By the analysis of intermediates of degradation of 2-chlorophenol,its possible degradation pathway is brought up.
