用光催化剂TiO_2降解2,2-二氯乙烯基二甲基磷酸酯的研究

A Study on the Photocatalytic Degradation of Dimethyl-2,2-Dichlorovinyl-Phosphate by TiO_2

本文研究了不同晶型ＴｉＯ２对２，２－二氯乙烯基二甲基磷酸酯的光催化性能，并讨论了催化剂用量、光照时间、溶液的初始ｐＨ及Ｈ２Ｏ２和Ｆｅ３＋浓度等因素对光催化效果的影响。

Dimethyl-2,2-Dichlorovinyl-Phosphate (DDVP)were degraded in the presence of suspended TiO 2 by illumination with a high pressure mercury lamp.The effects of some parameters on the degradation,such as the crystal type of TiO 2,amount of TiO 2,pH of solution,time of illumination and concentration of H 2O 2 and of Fe 3+ ion were studied.
