应用气相色谱测定常用卫生杀虫剂有效含量的方法探讨

Determination of the Effective Content of the Pesticides by Gas Chromatography

应用气相色谱──程序升温法，同时完成对卫生杀虫剂残杀威、八氯二丙醚、胺菊酯、二氯苯醚菊酯等有效成分分析，证实是一种操作简单、准确度高、精密度高的新方法。测定有效成分的回收率在８４．７８～１０８．２％，变异系数在４．３１～５．４７％。

The effective content of the pesticides,such as arprocab,tetramethrin, octachlorodipropyl ether,permethrin were determinated by gas chromatography with program temperature. The method is that four pesticides wece deter minated with one column at the sametime,so it is very fast and simple, and the result was satisfied. The recovery ratio of all pesticides ranged from 84.8%～108.2%, with less than 5.47% relative standard deviation.
