顶空气相色谱法检测阳离子醚化剂中的环氧氯丙烷

Determination of Epichlorohydrin in Cationic Etherified Reagent by Headspace GC

建立了顶空气相色谱法测定醚化剂中残留的环氧氯丙烷的分析方法。结果表明：该方法简单、快捷,在4~100μg/g范围内线性良好（r〉0.999）,最小检出限为2μg/g,相对标准偏差为1.7%~6.8%,回收率为98.1%~101.1%。

Headspace GC method was developed for the analysis of residual amount of epichlorohydrin in cationic etherified reagent.The headspace conditions were optimized.The results showed that the method was simple and fast.The calibration curves presented good linear relationship in the range of 4~100μg/g（r0.999）.The detection limit of the method was 2μg/g.The relative standard deviation（RSD） of the method was 1.7%~6.8%.The recovery achieved 98.1%~101.1%.
