概述了吡虫啉（ｉｍｉｄａｃｌａｐｒｉｄ）在蔬菜上残留量的测定方法。样品以二氯甲烷为提取剂，氧化铝柱净化，反相高效液相色谱法测定。空白样品添加０００３～０００９ｍｇ的平均回收率为８９３０％～９５６７％。最终残留量均低于００１ｍｇ／ｋｇ。降解半衰期２１～２９天。 The method of determination of residues of imidaclaprid in vegetables is summarized. Samples were extracted with dichloromethane, alumina column purification, determination by reversed-phase high performance liquid chromatography. The average recovery of blank samples from 0003 ~ 0009mg was 8930% ~ 9567%. The final residues were less than 0  01mg / kg. Degradation half-life 2  1 ~ 2  9 days.
