| 摘 要： | 用HPLC定量分析阿维菌素和毒死蜱混配的农药,色谱条件：250mm×4.6mm,5μm粒径的VP-ODS不锈钢柱;流动相：乙腈∶水∶冰乙酸=85∶15∶0.4（V/V）;流速：1.0mL/min;可变紫外检测器：波长245nm。本方法阿维菌素在1～16μg进样范围内和峰面积呈线性,毒死蜱在5～80μg进样范围内和峰面积呈线性。阿维菌素和毒死蜱的相关系数值（R）分别为为0.9999、0.9953。阿维菌素分析的回收率99.84%～101.0%,变异系数〈2%。毒死蜱分析的回收率在98.68%～100.22%,变异系数〈2%。

| Abstract: | A HPLC method for determination of abamectin .chlorpyrifos EC was studied. A stainless steel Column,250mmx4.6mm （i.d.） packed with VP-ODS 5μm was employed. A mixture of acetonitrile＋water＋acetic acid =85 ＋15 ＋0.4 （V/V） was used as mobile phase with a flow rate of 1.0mL/min.The detection wavelength was 245nm. This method was linear and reproducible over the range of 1 -16μg and 5-80μg analyte for abamectin and chlorpyrifos respectively. The linear corelation coefficients for abamectin and chlorpyrifos were 0.999 9 and 0.995 3 respectively. The recoveries were 99.8%-101% and 98.7%-100%. The coefficients of variation were both less than 2% for abamectin and chlorpyrifos respectively. |
