摘要
采用顶空气相色谱法测定了烷基醇聚氧乙烯醚中的二口恶烷。研究了顶空条件,标准曲线的相关系数为0.9989,检出限为20μg/L,回收率为91.6%~97.6%,相对标准偏差小于2.5%。
In this paper, dioxane in alkyl alcohol polyoxyethylene ether has been determined by headspace gas chromatography. The standard curve and headspace detection conditions are given. Correlation coefficient is 0998 9. The recoveries of dioxane ranged from 916% to 976%. The relative standard deviations were less than 25%. The limit of determination was 20μg/L. The method is simple, fast and accurate with higher sensitivity, less interference and better reproducibility.
