| 摘 要： | 本研究采用负载型TiO2膜作为催化剂降解有机磷农药敌敌畏，探讨了光催化反应时间、溶液的初始浓度对敌敌畏降解率的影响。试验表明，不同初始浓度的敌敌畏在经过90minUV／TiO2处理后，降解率都能达到90％以上，而且降解率随光照时间的增长而增加，随初始浓度的增加而降低。本研究采用毛细管柱气相色谱检测敌敌畏的剩余浓度，检出效果较好，并通过色谱图探讨敌敌畏的降解过程。

| Abstract: | The study investigated the photoeatalytic degradation of organophosphorus pesticides, dichlorvos, by using fixed TiO2, discussed the factors of influencing degradation rate of diehlorvos, such as irradiation time, initial concentration of solution, etc. The study showed that the photoeatalytic rate of dichlorvos solution of different concentration reached 90%. The degradation rate of diehlorvos increased with the extend of illumination time and decreased with the enhance of initial concentration. The concentration of dichlorvos were detected by capillary gas chromatography with good detective effect. It also discussed the degradation process of dichlorvos. |
