摘要
该文阐述了水中甲霜灵残留量的气相色普仪分析检测方法,研究了两种不同光源对甲霜灵在水中光化学降解的影响。结果表明,当甲霜灵添加浓度在0.05mg/L～5mg/L时,回收率变幅为83.85%～91.80%,相对标准偏差在2.50%～6.44%,在不同光源照射下,甲霜灵于纯水中的光解速率有显著的差异,表现为高压汞灯>太阳光。
An analytical method for metalaxyl in water was established by gas chromatography in this paper Applying this method, the respective effect of two kind of light sources on photo-degradation of metalaxy were studied. The results showed that： Adding concentration of matalaxl at level of 0.05, 0.1, land 5mg/L,the recovery rate ranged from 83.85% to 91.80%and the relative standard deviation was 2.50% - 6.44%. The photolysis rate of metalaxyl in the pure water was HPML〉 sunlight.
