气相色谱法快速测定家用气雾杀虫剂中丙烯菊酯、氯菊酯、增效醚含量

用气相色谱法定量测定了家用气雾杀虫剂中的丙烯菊酯、氯菊酯和增效醚。色谱柱为５％ＱＦ－１／Ｃｈｒｏ－ｍｏｓｏｒｂＷＨＰ，以邻苯二甲酸二苯酯为内标物，测得的回收率分别为１００％，１０２％，９９．９％；变异系数为０．１３，０．５６，０．４８，方法简便、快速、准确。

Rapid Determination of Allethrin, Permethrin and Piperonyl Butoxide in Insecticidal Aerosol for Household by Gas Chromatography

A method of quantitative analysis for allethrin, permethrin and piperonyl butoxide in insecticidal aerosol for household has been studied by GC-FID. The gas chromatographic conditions were as follows. column:packed with 5% QF-1 on Chromosorb W HP, column temperature: 215 degrees C, temperature of injector and detector 250 degrees C and carrier gas: N2 15 mL/min. Diphenyl phthalate was used as the internal standard. All components and internal standard were separated in 7 min. For allethrin, permethrin and piperonyl butoxide, the recovery were 100%, 102% and 99.9%, and the coefficients of variation were 0.13, 0.56 and 0.48 respectively. The method is simple, rapid and accurate.
