RP-HPLC ANALYSIS OF CARBONYL COMPOUNDS IN SOME INDOOR AIR SAMPLES IN A FACULTY FROM CLUJ-NAPOCA.

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). [ABSTRACT FROM AUTHOR]
