摘要
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。
The GC method was developed for determination of beta-cypermethrin and propoxur in their complex SC. In this method, dicyclohexyl phthalate was used as internal standard, FA was heat stabilizer, then beta-cypermethrin and propoxur were detected by temperature programming method. The results showed that the addition of heat stabilizer FA could inhibit decomposition effectively, the relative standard deviations of beta-cypermethrin and propoxur were 0.77% and 0.52%. The method was accurate, simple, rapid, and had good stability.
