摘　　要：通过基质固相分散净化,气相色谱-电子捕获检测器(GC-μ-ECD)检测,建立了竹笋中7种农药多残留测定方法,实现了对竹笋中六六六、滴滴涕、五氯硝基苯、甲氰菊酯、氯氰菊酯、三氟氯氰菊酯和毒死蜱农药多残留的同时测定。在0.05～0.2 mg/kg添加水平下,7种农药的回收率在82.2%～123.5%之间,相对标准偏差(RSD)均小于6.1%。该方法适用于竹笋中农药多残留的检测。A multi-residual analytical method was developed for the simultaneous determination of seven pesticides in bamboo shoot based on matrix solid-phase dispersion（MSPD） extraction coupled with gas chromatography-electron capture detector（GC-μ-ECD）.The average recoveries of these pesticides at spiked levels of 0.05-0.2 mg/kg ranged from 82.2% to 123.5% with the relative standard deviation（RSD） below 6.1%.The proposed method was sensitive and reliable for the determination of 7 pesticide residues in bamboo shoot.
