摘要
以Chromosorb106吸附管吸附环境空气中的微量乙酸,样品经自动热脱附仪解吸,用HP-20M色谱柱分离,氢火焰离子化检测器检测,方法最低检出浓度为0.10mg/m3,相对标准差为5%以下,加标回收率在86～105%之间。方法操作简便、快速,适用于环境空气中微量乙酸的监测。
Sampling with the sorbent tube of Chromosorb106, and then desorbing with automated thermal desorber, sample would be separated by HP-20M column and analyzed by gas chromatography. Using the sorbent concentration method,the lowest detection limit of acetic acid was 0.10mg/m^3 .RSD was found to be below 5%, recovery found for acetic acid was in the range of 86%～105%.The method is convient ,fast and has applied to determination of acetic acid in ambient air.
