摘　　要：建立气相色谱程序升温法同时分析氰戊菊酯和马拉硫磷含量的方法。色谱柱为Rtx-1毛细管色谱柱,癸二酸二正丁酯为内标物,丙酮为溶剂。实验表明,氰戊菊酯和马拉硫磷的线性相关系数分别为0.996 4和0.998 4,变异系数分别为0.308 6和0.240 1,平均回收率分别为99.57%和99.78%。A programmed temperature gas chromatography method for simultaneous determination of fenvalerate and malathion content was established.The column was Rtx-1 capillary column,n-butyl sebacate as internal standard and acetone as the solvent.Experiment showed that： fenvalerate and malathion linear correlation coefficients were 0.996 4 and 0.998 4,the variation coefficients were 0.308 6 and 0.240 1,the average recoveries were 99.57% and 99.78%.
