摘　　要：研究了水溶液中邻苯二甲酸二甲酯的臭氧氧化 .考察了pH值、温度、臭氧用量等对反应的影响 .结果表明 :臭氧氧化使溶液的总有机碳 (TOC)减少 ,并使紫外(UV)吸收大大降低 ;毛细管电泳 (CE)分析证明有邻苯二甲酸的中间产物产生 .采用Mn(Ⅱ )催化臭氧氧化 ,TOC去除率大大提高 .The ozonation of dimethyl phthalate in aqueous solutions was studied.The effects of pH,temperature,ozone dosage and initial concentration on the degradation of dimethyl phthalate were investigated.Results showed that ozonation allowed reduction of total organic carbon(TOC)and provided an effective means of removing UV absorption.The mechanism of degradation was explored primarily.Phthalate acid,as a intermediates formed during the ozonation was detected by capillary electrophoresis(CE)analysis.The removal of TOC was greatly enhanced by Mn(Ⅱ)-catalysed ozonation.
