本文用反相高效液相色谱法测定灭多威在蔬菜中的残留量。本法准确、简便、灵敏，检出限为０．１ｎｇ，线性范围为１．０～４０μｇ／ｍｌ，高、中、低３种浓度平均加标回收率为８９．７％～９６．１％，变异系数小于５％。
In this paper, the determination of methomyl residues in vegetables by reversed-phase high performance liquid chromatography. The method was accurate, simple and sensitive. The detection limit was 0.1ng and the linear range was 1.0 ~ 40μg / ml. The average recoveries for the three concentrations were 89.7% ~ 96.1% , The coefficient of variation is less than 5%.
