采用气袋直接进样法测定环境和污染源空气中的丙烯腈.结果表明:丙烯腈在0.4～99.5mg/m3浓度范围内具有良好的线性关系,相关系数为0.999 8.在低、中、高3个添加水平回收率为88.9％～100％,相对标准偏差为0.6％～4.7％,均能较好地满足实验室分析要求.%Acrylonitrile in air environment and air pollution sources was determined by direct injection into airbag. The results showed that calibration curve of acrylonitrile in concentration range of 0.4~99.5 mg/m was linear,and the correlation coefficient was 0.999 8. The recoveries at three levels of low,middle and high were in the range of 88.9%~100%,relative standard deviation were in the range of 0.6%~4.7%,which could met the requirements of lab analysis.
