| 摘 要： | 采用纳米TiO2光催化降解甲胺磷农药，分别测定分析了PO^3-4,有机磷农药，COD等，以说明光催化降解甲胺磷的情况，结果说明纳米TiO2光催化降解甲胺磷是可行的，根据我们及他人光催化降解有机磷农药的实验结果，比较了分别通过测定TOC，CO2，PO^3-4，有面农药，COD等各种不同的分析方法来衡量光催化降解效率，以评定催化剂的活性及光催化法的可行性的优缺点，以便根据样品的实际情况以及实验室所具备的仪器设备，选择合适的分析方法。

| Abstract: | The photocatalytic degradation of methamidophos by TiO2 nanometre powder was investigated in this paper. The photocatalytic degradation of methamidophos was proven to be possible by determining the concentration of PO3-4, methmidophos, COD. According to our and other peoples experimental results of photocatalytic degradation of Organophosphorous pesticides, we compared the methods of calculating the degradation efficiency of Organophosphorous pesticides by determining the concentration of TOC, CO2, PO3-4, methamidophos and COD. The activity of catalysts and the feasibility of photocatalytic degradation could be assessed by degradation efficiency. So the best method could be chosen on the base of the real sample and the apparatus in the lab. |
