| 摘 要： | 采用sol-gel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,对内分泌干扰物质双酚A的光催化降解反应.分别讨论了pH值、H2O2的加入量、双酚A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=4,30 mg/L的H2O2中对初始浓度为50 mg/L的双酚A溶液光照180 min有较好的降解效果.

| Abstract: | The photocatalytic degradation of bisphenol A(BPA),one of the endocrine disrupting chemicals (EDCs), was studied. The photocatalyst was TiO_2 thin film (preparing by sol-gel method). The reaction proceeded using a 125 W mercury lamp as ultraviolet light resource. The influences of various parameters were studied. The results show that the best condition for photodegradation of BPA is pH=4,30 mg/L H_2O_2 and 180 min irradiation. |
