顶空气相色谱法检测卫生用纸中的氧乙烯基含量

Determination of Oxyethylene Groups in Tissue Paper by Headspace Gas Chromatography

本文建立了一种基于顶空气相色谱技术的卫生纸和纸巾纸中氧乙烯基含量的检测方法,该方法通过萃取、浓缩、高温反应等过程,将样品中的氧乙烯基转化为能够用顶空气相色谱检测的碘乙烷,与传统方法相比本文方法简便、安全、灵敏度高。

This paper reports a headspace gas chromatographic technique for determination of oxyethylene groups in tissue paper. The oxyethylene groups of polymers in tissue paper were converted to iodoethane in hydroiodic acid medium in a closed vial after sample extraction and concentration. The iodoethane was then detected by headspace gas chromatography. The present method is simple, safety and high sensitivity compared with the traditional method.
