摘　　要：本文用GC—9A气相色谱仪，OV—17玻璃填充柱，快速程序升温时黄瓜中敌敌畏、甲基地硫磷，马拉硫磷等3种有机磷农药混合残留量送行分离测定。样品经二氯甲烷提取，活性炭净化处理，回收率力82．88～98．87％，变升系数为1．06～5．13％，最小检出浓度为0．0544～0.107mg.ml-1。GC determination of methyl—parathion, malathion, DDVP were reported in the paper. Specimen is treated with CH2 Cl2 activated carbon. It is a simple and convenient method. Residues of pesticide in the spedment are separated and deteined by programmed temperature gas chromatography. Recovery ratio 82. 88—98.87%. Comparatively standard variance 1. 06—5. 13%. Limit of determination 0. 0544 —0. 107ug. ml-1
