摘要
目的:建立了空气中丙酮的气相色谱应急监测方法。方法:利用便携式大气采样器采集空气中气态丙酮,水吸收后经气相色谱分离,并用氢火焰离子化检测器(FID)测定。结果:本方法操作方便快捷,平均回收率大于95%,相对标准偏差小于3%。结论:本方法适合环境空气及工作场所空气中丙酮浓度的应急监测。
A method of emergency monitoring of acetone in air with gas chromatography（GC） was estabisheel. Methods： Aromatic acetone in air were absorbed by water in the portable air sample,and separated through GC and detected by flame ionization detector （FID）.This method is convenient and easy to operate, the average recoveries were more than 95%.The relative standard deviations were less than 3%.This method is adaptable to emergency monitoring of acetone concentration in the air of environment and workplace.
