摘要
采用solgel法制备TiO2薄膜。以该薄膜为催化剂,研究了在H2O2存在的条件下,对内分泌干扰物质邻苯二甲酸乙酯(DEP)的光催化降解反应。分别讨论了pH值、H2O2的加入量、DEP的初始浓度以及光照时间对降解反应的影响。结果表明在pH=2、50mg/L的H2O2中对初始浓度为50mg/L的DEP溶液光照150min有较好的降解效果。
The photocatalytic degradation of diethyl phthalate (DEP). one of the Endocrine Disrupting Chemicals (EDO, was studied, with TiO2 thin film prepared by sol-gel method as photocatalyst and a 125W mercury lamp as ultraviolet light source. The influences of various parameters were studied. Results showed that the best photodegradation of DEP is under the condition of pH 2, 50mg/L H2O2 and 150min irradiation.
