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 contents of avermectin and chlorpyrifos in the mixture were quantitatively analyzed on the same column with C18 column and UV detector using high performance liquid chromatography with V (methanol): V (water) = 85:15 as mobile phase. The results showed that the standard deviations of avermectins and chlorpyrifos were 0.0055 and 0.0669, respectively. The coefficients of variation were 2.75% and 0.3367%, respectively. The average recoveries were 99.63% and 99.82%, respectively. The linear correlation coefficients were abamectin = 1, r chlorpyrifos = 0.9995.
