摘要
[目的]建立水中丙烯腈的气相色谱测定方法.[方法]采用小体积直接进样,用DB-FFAP毛细管柱程序升温分离,氢火焰离子化检测器检测,以保留时间定性,外标法定量.[结果]该方法相对标准偏差低于5.0%,加标回收率为95.7%~ 101.0%,标准曲线相关系数大于0.999,检出限为0.03 mg/L.[结论]该方法适用于地表水中丙烯腈的测定.
Abstract
[Objective] A gas chromatographic method was developed for the determination of acrylonitrile in water samples.[Method] Acrylonitrile was separated through DB-FFAP capillary column and determined by GC-FID.Retention time of the peak was used for qualitative analysis,while external standard method was used for quantitative analysis.[Result] The results indicated the relative standard deviation was less than 5.00%,and the average recovery was 95.7-101.0%.The correlation coefficient of the standard curve was more than 0.999,and the method detection limit was 0.03 mg/L.[Conclusion] This method can be used for the determination of acrylonitrile in water samples.
