Abstract

This study describes a reversed-phase high-performance liquid chromatography (RP-HPLC) method for the analysis of several

carbonyl compounds in air samples. The air samples were collected using a passive sampling method and cartridges based on

florisil impregnated with 2,4-dinitrophenylhydrazine (2,4-DNPH). After derivatization the carbonyl compounds were analyzed

by liquid chromatography technique coupled with UV detection. The developed RP-HPLC method was used to analyze eight

carbonyl compounds in air samples collected from the indoor environment of a faculty building located in Cluj-Napoca. The

analyses results indicated the presence of three carbonyl compounds: propionaldehyde (2.65-3.14 μg/m3), acetaldehyde (10.45-

26.91 μg/m3), and acetone (44.96-89.88 μg/m3).
