反相高效液相色谱法测定土壤中微量灭多威

Reversed-phase High Performance Liquid Chromatographic Determination of Methomyl in Soils

研究了土壤中灭多威的最佳提取分离方法和ＨＰＬＣ的测定方法。测定土壤中灭多威的检测限为０．１ｎｇ，线性范围１．０－２０μｇ／ｍｌ，高、中、低３种浓度的平均加标回收率为９６．１％－１００．２％，变异系数小于５％。本法操作简便，准确度高、精密度好，其它杂质基本不干扰。

A reversed- phase HPLC method was discribed for determination of methomyl in soils. The detection limit of methomyl in soils was 0. 1μg,and the linear range was 1. 0- 20μg/ml. The average recovery of methomyl as standard added to soils as in the range of 96. 1 % - 100. 2%. The relative standard deviations were below 5%. This method was simple with a higher sensitivity and a bether accaracy.
