| Abstract: | Acrylonitrile in ambient air was collected by Tenax GC and then thermo desorbed. It was separated on GDX 502 chromatographic column from other pollutants and determined by flame ion ization detector The minimum detectable concentration was 0 01 mg/m\ 3 when 2 L ambient air was collected The recoveries were 85 6% 105 4% and RSDs were 4 5% 6 2%. |
