乙草胺和嗪草酮混合悬乳剂的气相色谱分析

Gas Chromatographic Determination of Acetochlor and Metrihuzin in Suspoemulsion Mixture

本文报道了乙草胺和嗪草酮混合悬乳剂的气相色谱分析方法。在４％ＯＶ－２２５／ＣｈｒｏｍｏｓｏｒｂＷ－ＨＰ（８０～１００目）色谱柱上乙草胺、嗪草酮和内标物癸二酸二丁酯的保留时间分别为１０．４５，１７．２４和１２．９分钟，实现了良好的分离。乙草胺的标准偏差、变异系数和回收率分别为０．１０９、０．５６％和９９．６％；嗪草酮的标准偏差、变异系数和回收率分别为０．３１４、１．５２％和１００．１％。

A gas chromatographic method was developed for simultaneous determination of acetochlor and metribuzin in suspoemulsion mixture. Retention times for acetochlor,metribuzin and internal standard dibutyl sebacate on 4% OV-225/Chromosorh W-HP were 10. 45, 17. 24 and 12. 90 minutes, respectively. Standard deviation, coefficient of variation and recovery were 0. 109, 0. 56% and 99. 6% for acetochlor,and 0. 314, 1. 52% and 100. 1% for metribuzin. respectively.
