建立了气相色谱法同时测定15%高氯·残杀威悬浮剂中有效成分。方法以邻苯二甲酸二环己酯为内标物,以FA为稳定剂,采用程序升温法对高效氯氰菊酯、残杀威进行了气相色谱分析研究。结果表明,热稳定剂FA的加入能有效抑制高效氯氰菊酯和残杀威分解,两者相对标准偏差分别为0.77%和0.52%。该方法准确、简便、快速,稳定性好。 A gas chromatographic method was developed for the simultaneous determination of the active ingredients in 15% high-chlorinated pesticides suspension. Methods Dicyclohexyl phthalate as internal standard and FA as stabilizing agent were used to study the gas chromatographic analysis of beta-cypermethrin and propoxur. The results showed that the addition of FA could effectively inhibit the decomposition of beta-cypermethrin and propoxurone, with relative standard deviations of 0.77% and 0.52%, respectively. The method is accurate, simple, fast and stable.
