| Abstract: | This paper provides a method to determinate the volatile chemical compounds of aldehydes and ketones in air and exhausted gas.The compounds are absorbed by the acidic saturated solution of 2,4 dinitrophenyl hydrazine(DNPH)and converted to their hydrazones respectively.The hydrazones are then extracted with CS 2 and separated and determinated using Gas Chromatograph (GC FID,fixed phase:3%SE 30/chromosorb W HP,80 100 mesh).The result of determination of Formaldehyde,A cetaldehyde,Acrolein,Acetone,Butyl aldehyde,Butanone,Methyl isobutanone and so on in air and exhausted gas is fair satisfied. |
