摘　　要：建立了气相色谱测定水果中2,4-滴丁酯残留量的简单快速的方法。水果样品经提取、净化、浓缩后,用带有ECD检测器的气相色谱仪检测2,4-滴丁酯的残留量。方法的最低检出限0.005mg/kg,样品中2,4-滴丁酯平均添加回收率在74.60%～99.70%之间,变异系数在3.12%～7.76%之间。A simply and rapid method was established for determining acetamiprid residues in fruits through the experiment by gas chromatography. Sample were extracted, cleaned up, derivatived and subjected to gas chromatography with ECD detection. The lowest detectable concentration in fruits samples were 0.005 mg/kg. Sample recoveries ranged from 74.60 to 99.70%. The coefficients of variation from 3.12 to 7.76%.
