摘　　要：采用溶胶-凝胶法制备钇掺杂TiO2光催化剂,经FT-IR、XRD表征,表明粉体为锐钛矿,晶粒尺寸为8.8nm.在9W日光灯照射下,Y-TiO2催化降解高效氟氯氰菊酯和p,p’-DDE,光催化降解试验发现75min后高效氟氯氰菊酯和p,p’-DDE的降解率分别为83%和75%.Photocatalyzer doped titania with yttrium （Y-TiO2）, was synthesized by sol and gel methods. It was characterized by FT-IR and XRD. The signal phase of Y-TiO2 indicated that it was analysed and its crystal particles size was 8.Snm. The Y-TiO2 was employed for the photocatalytic degradation of cyfluthrin and p,p＇-DDE under irradiation of 9W lamplight in 75 min. The results showed that the degradation of cyfluthrin and p,p＇-DDE were 83% and 75%, respectively.
