摘　　要：提出了采用高效液相色谱法,使用Hypersil C18不锈钢色谱柱和乙腈-水（85＋15）混合溶液为流动相进行分离,并用紫外检测器在220 nm波长处同时测定胺菊酯和右旋苯醚菊酯,此方法用作上述两杀虫剂的复合制剂0.3%胺菊酯.右旋苯醚菊酯气雾剂的质量监控分析方法。测得两化合物的相对标准偏差（n=5）依次为0.86%和2.6%,回收率依次在94.7%~105.5%和92.8%~102.9%之间。HPLC was applied to the simultaneous determination of tetramethrin and d-phenothrin using Hypersil C18 stainless steel chromatographic column and the mobile phase of acetonitrile-water（85＋15） mixture for separation,and UV-detection at the wavelength of 220 nm in the determination.The proposed method was feasible to be used for control analysis of the compound insecticide 0.3% tetramethrin·d-phenothrin aerosol.Values of RSD′s（n=5） found were 0.86% for tetramethrin and 2.6% for d-phenothrin,and values of recovery found were in the ranges of 94.7%-105.5% and 92.8%-102.9% respectively.
