摘要
便携式气相色谱-质谱仪(GC-MS)能同时对多组分复杂有机物进行定性、定量分析,在环境监测尤其是事故现场应急监测中发挥越来越重要的作用。文章建立了便携式顶空-GC-MS选择离子测定水中丙烯醛、丙烯腈的分析方法,其相关性大于0.997,检测限为5~10μg/L,回收率为93.3%~99.5%,该方法适用于水中丙烯腈、丙烯醛的应急现场及日常实验室分析工作。
Portable gas chromatography mass spectrometry (GC-MS) can simultaneously carry out qualitative and quantitative analysis of multi-component complex organic compounds and plays an increasingly important role in environmental monitoring, especially in the spot emergent monitoring. The Method of Fast Determination of Acrolein and Acrylonitrile in Water was established by the portable headspaee gas chromatography and mass spectrometry (GC-MS) in this paper. It is suitable for environmental emergency monitoring and laboratory for analysis of acrolein and acrylonitrile in water because this method possessed relativity r 〉 0. 997, detection limits 5-10 μg/L and the average recoveries 93.3% -99.5%.
