| Abstract: | 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. |
