摘要
研究了以悬浮态TiO2 为催化剂,在波长为365nm的125W紫外灯照射下加入H2O2 对邻苯二甲酸乙酯(DEP)光催化降解,分别讨论了pH值、H2O2 的加入量、邻苯二甲酸乙酯的初始浓度及光照时间对DEP的降解效果。结果表明:在pH=2、浓度为50mg/l的H2O2 中对初始浓度为50mg/L的邻苯二甲酸乙酯溶液光照120分钟有较好的降解效果。
The photocatalytic degradation of diethyl phthalate(DEP), one of the Endocrine Disrupting Chemicals (EDC), was studied. The photocatalyst was TiO 2 suspension. The reaction proceeded using a 125W mercury lamp as ultraviolet light resource. The influences of various parameters were studied. The results show that the best condition for photodegration of DEP of 50mg/L is pH=2,50mg/LH 2O 2 and 120min irradiation.
