Abstract:

The determination of aldehydesand ketones in air has been studied in this paper. In the method mentioned here, aldehydes and ketones in air are separated and determined by pouring the methanol acidic solution of 2.4 dinitrophenylhydrazine directly into liquidchromatograph. The study manifests that the method is fast, convenient and good in repeatability and separation, and that the accuracy and precision of the test coincides with the demand of the permissible error of microchemical analysis.

Key words: Aldehyde and ketone, liquid phase, Chromatography, determination
