Detection and Analysis for Aldehyde and Ketone in Engine Exhaust

Keywords: Engine exhaust; Aldehyde and ketone; 2,4
-Dinitrophenylhydrazine; High performance liquid chromatography
Details
Abstract: The method of sampling engine exhaust for aldehyde and ketone was based on the reacting carbonyls with 2,4 -dinitrophenylhydrazine ( 2,4-DNPH) coated on an adsorbent cartridge,followed by a high perfomance liquid chromatographic method which was established to determine the five carbonyl compounds including formal dehyde. Characteristics of carbonyls emissions from 92# gasoline were investigated and it was showed that formaldehyde was the most abundant carbonyls in the exhaust,followed by acetaldehyde.
