| 摘 要： | 以高压汞灯和太阳光为光源,以不同波长滤光片处理得相应波长区域,研究了乙草胺在水中的光解动态。结果表明:在胡敏酸存在下,乙草胺的光解动态符合一级动力学规律,其光解速度随着照射光波长的延长而减慢,光解半衰期延长,与未用滤光片处理的对照相比,差异极显著,表明乙草胺在水中的光解速度与照射光波长关系极大。

| Abstract: | The photodegradation kinetics of acetochlor in water was studied under the treatment of the illumination of high-pressure mercury lamp and sunlight by the different wavelength filter.The photo-(degradation) kinetics of acetochlor accorded with the first order kinetic equation at the presence of(Humic) acid,the photodegradation rates of acetochlor slowed down as wavelength extending,the photodegradation halflife of(acetochlor) prolonged.The marked diversity was observed as compared with no filter treatment.It(indicated) that the photodegradation of acetochlor in water was significantly related to light wavelength. |
