摘要
建立气相色谱-质谱法测定土壤中有机磷和氨基甲酸酯类农药残留分析方法。以丙酮-石油醚(体积比为3∶1)为提取剂,采用超声波提取土壤中农药残量,经弗罗里土层析柱净化,气相色谱-质谱以选择离子监测法同时测定土壤中多种有机磷和氨基甲酸酯类农药,取得了较好的效果。在0.1、0.5μg/mL两个质量浓度添加水平的回收率分别为70.1%～119.0%和78.1%～119.0%,相对标准偏差分别为6.30%～9.80%和5.20%～8.23%。
GC-MS method was used to determine organophosphorous and carbamates pesticide residues in soil sample.The pesticide residues were extracted from soil sample by ultrasonic using acetone-petroleun ether(volume ratio 1∶3)as extractant were cleaned up with Florisil column and analyzed by GC-MS-SIR in the same time.The recoveries obtained from samples spiked with standards at the concentration levels of 0.1 μg/mL and 0.5 μg/mL were in the ranges of 70.1%～119.0% and 78.1%～119.0%,respectively,with relative standard deviations of 6.30%～9.80% and 5.20%～8.23%,respectively.
