几种农药对辛硫磷光降解影响的研究

The Photosensitive Effects of Five Pesticides on Photodegradation of Phoxim

以太阳光为光源，研究呋喃丹等５种农药对辛硫磷在玻片表面光分解的影响。结果表明，辛硫磷极易发生光解，光解半衰期小于４６．１４分钟，且光解速度与光强度成正相关；呋喃丹等５种农药均显著地加快辛硫磷的光解，起着明显的敏化光解作用。

The photodegradation effects of parathion -methyl,carbofuran, cypermethrin, deltamethrin, and triadimefon on phoxim were studied on glass surface in sunlight. The photodegradation rate of phoxim was very fast, and its half-life was below 46. 14min.. The photodegradation rate of phoxim was accelerated significantly by parathion-methyl, carbofuran, cypermethrin, deltamethrin and triadimefon.
