气袋直接进样法测定丙烯腈
Determination of Acrylonitrile by Direct Injection into Airbag
-
摘要: 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0.4~99.5 mg/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。Abstract: 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/m3 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.
