Abstract:Determination of acetaldehyde,acrolein and formaldehyde in water by GC coupled with purge and trap was studied.After working parameters optimizing,experimental results show that the advantages of this method is simple,sensitive and high efficient.DL(detection limit) of the target compounds was 0.037,0.012 and 0.0006mg/L,respectively.RSD(Relative standard deviations) was ranged from 3.9% to 15.8%,and the recovery were 73.0%~118%.This method could meet the monitoring requirement of target compounds in Environ...
Keywords:Purge and trap  Acetaldehyde  Acrolein  Formaldehyde  Gas chromatography
