摘　　要：目的:建立用气相色谱检测促干剂中33种农药残留的分析方法。方法:用气相色谱法,样品以乙腈为提取剂,弗罗里硅土柱层析净化,分别用ECD和FPD检测器进行定性定量分析。结果:33种农药在0.005～0.50mg/L的范围内具有良好的线性关系,相关系数大于0.991。在添加量范围平均回收率为82.4%～114.1%,变异系数(RSD)为0.5%～13.0%。结论:该方法准确性、精确性和灵敏度均满足农药残留分析的要求,简便、快捷,。A method was developed for the multiresidue determination of 33 pesticides in Dry-promoter by gas chromatography with ECD and FPD.A good linear relationship with a determination coefficient above 0.991 was found f for the 33 pesticides in the range of 0.005-0.5 mg/L.The mean recoveries for the 33 pesticides ranged from 82.4%to 114.1% in a blank sample of Dry-promoter with a relative standard deviation（RSD）between 0.5% and 13.0%.The method was accurate,precise and sensitive,and therefore could meet the requirements for pesticide residue analysis.
