摘　　要：邻苯二甲酸酯类(PAEs)作为塑料的改性添加剂在塑化剂市场中占主导地位且在水环境中大量检出,对水生生物及人类健康存在潜在的威胁.光催化氧化技术对水体中PAEs的降解有着重要的作用,文章综述了光照时间、光照强度、催化剂投加量、PAEs初始浓度、反应溶液p H及添加剂等因素对PAEs的光催化降解的影响,阐述了PAEs的光催化降解动力学及其光催化降解机理,同时探讨了光催化氧化降解PAEs的趋势.Phthalic acid esters （PAEs） paly a dominant role in the plasticizer market and have been widely detected in water. Existence of PAEs in water has already been a threat to the aquatic organisms and human health. This paper summarized the degradation of PAEs by photocatalytie oxidation technology： the effects of PAEs on the removal efficiency by such factors as irradiation time, irradiation intensity, catalyst dosage, initial concentration of PAEs, pH value of reaction solution and additives; the reaction dynamics of PAEs decomposition; and the degradation pathway of PAEs. At last, the further research was discussed.
