Abstract: A procedure for determination of nitrophenols and nitrocresols in gaseous samples was proposed. The analytes from samples were absorbed in NaOH solution. The alkaline solution was extracted with dichloromethane to remove the neutral and basic interfering compounds. After acidification of the absorption solution the analytes were extracted into dichloromethane and analysed by gas chromatography on capillary column with polydimethylsiloxane stationary phase. Detection limits of individual analytes 0.1-1.4 mg m-3 in gaseous samples were achieved.
