摘要：

摘要：样品经正己烷提取，弗罗里硅土固相萃取小柱净化，气相色谱仪检测。对菜豆和土壤中的精异丙甲草胺进行不同水平的添加回收率实验，方法的回收率为84.47％～105.92％，变异系数为0.87％～7.81％。精异丙甲草胺的最小检知量为1×10-11 g，它在土壤、植株、菜豆上的最低检出质量分数为0.01mg?kg-1。方法的精密度、灵敏度和准确度符合农药残留分析的要求。

Abstract:

Abstract: A determination method of S-metolachlor residue was established by GC equipped with a ECD detector. The sample was extracted by n-hexane, cleaned by florisil-SPE column. The average recoveries of the method ranged from 84.47％～105.92％，and the coefficient of variation was 0.87％～7.81％. The lowest detectable concentration of soil, plant and bean were 0.01mg?kg-1, respectively. The sensitivity, accuracy and precision of this method were satisfied for pesticide residue analysis.
