摘　　要：采用吹扫捕集-气相色谱测定水中丙烯腈、丙烯醛,优化试验条件。该方法具有较高的灵敏度、良好的线性、方法简便。丙烯腈检出限为0.002 mg/L;丙烯醛检出限为0.003 mg/L,标准样品测定的相对标准偏差为3.2%,实际样品的加标回收率为80.0%～110%。The method is established to determine acrylonitrile and acrolein in Water by purge and trap - Gas Chromatography. It is a method with high sensitivity, good linearity, lower detect limit and can be easily operated as well. The detect limit of Aerylonitrile is 0. 002 mg/L while the hmit of Acrolein is 0. 003 mg/L. The relative standard deviation when analyzing a standard sample runs at 3.2% and it has a 80% - 110% rate of recovery.
