摘    要:研究以TiO2粉末作为光催化剂,光降解3种不同结构的有机磷农药的可行性。结果表明,有机磷农药结构不同其光降解率不同;浓度1.0×10-4mol/L的4种有机磷农药,375W中压汞灯照射40min有机磷将完全转变为无机磷,并检测出人效磷农药催化降解的部分中间产物。研究光催化剂TiO2的用量、空气流量、外加Fe3+浓度对光催化降解的影响,并初步探讨了机理。

关 键 词:有机磷农药  光催化  降解  二氧化钛粉末  废水处理

Abstract:The feasibility of photocatalytic degradation of three different structures's organophosphorus pesticides using TiO2 powders as a photocatalyst was studied. The results show that different structpos of organophosphorus pesticides had different photodegradation efficiencies,and four organophosphorus pesticides of 1.0×10-4 mol/L were completely photocatalytically degraded into inorganic phosphste after 40min illumination with a medium pressure mercury lamp of 375 W.Some intermediate products of photocatalytic degradation of monocrotophos were detected and the effects of the Parameter,such as amount of TiO2,flow rate of air and Fe3+ concentration,on the photocatalytic degradation were also investigated. The mechanism were discussed preliminarily.
Keywords:organophosphorus pesticides  photocatalytic degradation  TiO2 powders
