| 摘 要： | 采用sol—gel法制备TiO2薄膜光电极，以该电极为工作电极，铂丝为对电极，饱和甘汞电极为参比电极，对双酚A的光电催化降解进行了研究，结果表明：该电极具有“型半导体的特征行为．外加偏压为＋0．8V、pH=4，0．88mmol／L的H2O2中，对初始浓度为0．22mmol／L的双酚A溶液光照180min，降解率达70．24％，讨论了氧的存在、外加偏压、双酚A浓度和pH值等因素对光电催化反应的影响。

| Abstract: | A three-electrode system composed of Ti/TiO_2 prepared by sol-gel method as the working electrode,Pt wire as the counter electrode and saturated calomel electrode(SCE) as the reference electrode was used for the photoelectrocatalytic degradation of bisphenol A(BPA),one of the Endocrine Disrupting Chemicals(EDC).The results show that under the condition of pH=4,0.88 mmol/L H_2O_2,external potential(+0.8 V) and 180 min irradiation,the rate of photodegration of BPA(0.22 mmol/L) reaches 70.24%.The influences of various parameters were studied. |
