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 pH 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.

Abstract: 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 photocatalytic 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 furthe
