| 摘 要： | 研究以四异丙醇钛为原料，配制成胶体用玻璃纤维附载ＴｉＯ２的过程；同时利用附载的ＴｉＯ２光催化降解有机磷农药。结果表明，低浓度的４种有机磷农药，３７５Ｗ中 汞灯短时间照射有机磷将完全被光催化氧化至ＰＯ＾３－４；玻璃纤维上附载的ＴｉＯ２不易脱落。

| Abstract: | Photocatalytic degradation of organophosphorus pesticides using supported TiO2 as a catalyst,which is prepared by thermal decomposition and calcination of colloidal solution made from hydrolytic of titanium tetraisopropoxideTi(isoOC3H7)]ion fiberglass was studied.The results showed that four organophosphorus pesticides of lower concentrations were completely photocatalytically degraded into PO43- within a short time illumination with a medium pressure mercury lamp of 375 W.The TiO2 supported on the fiberglass was not removed easily,after 120 h illumination there was no significant loss of the photocatalytic activity of TiO2,it could be used continually.The reasons of the different chemical structures of organophosphorus pesticides affecting photodegradation efficiency were investigated. |
