摘　　要：叙述了采用高效液相色谱法以V(甲醇)∶V(水)=85∶15为流动相,C18柱和紫外检测器同柱定量分析了混合剂中的阿维菌素和毒死蜱的含量。结果表明,阿维菌素和毒死蜱的标准偏差分别为0.0055、0.0669;变异系数分别为2.75%、0.3367%;平均回收率分别为99.63%、99.82%,线性相关系数分别为r阿维菌素=1、r毒死蜱=0.9995。The quantitative analysis of mixture of abamectin and chlorpyrifos by reverse phase HPLC using methanol and water （85∶15）,C18 column and ultraviolet detector was described. The results showed the standard devitions for abamectin and chlorpyrifos were 0.005 5 and 0.066 9,the coefficients of variation were 2.75% and 0.336 7%,the average recoveries were 99.63% and 99.82%,the linear correlations were 1 and 0.999 5 respectively.
