摘要
建立了顶空-气相色谱法测定水中乙醛、丙烯醛和丙烯腈的分析方法。该方法分离度好，灵敏度高，水中乙醛、丙烯醛和丙烯腈的检出浓度为0．03mg／L、0．07mg／L、0．04mg／L，回收率分别为86％-115％、81％～110％、80％～108％。结果表明，顶空-气相色谱法测定水中乙醛、丙烯醛和丙烯腈方法简单快捷，准确，适合地表水、废水中乙醛、丙烯醛和丙烯腈的同时测定。
A headspace gas chromatography method was developed for acetaldehyde, acrylaldehyde and acrylonitrile in water. This method shows good separating effect and high sensitivity. The lowest detection limits were 0.03mg/L for acetaldehyde, 0.07mg/L for acrylaldehyde , 0.04mg/L for acrylonitrile. The recovery rates were 86% -115% for acetaldehyde, 81%-110% for amylaldehyde, 80%-108% for acrylonitrile. Experiment results show that the advantages of this method are simple, rapid, accurate for determination of acetaldehyde, acrylaldehyde and acrylonitrile in surface water and wastewater.
