A procedure for determination of nitrophenols and nitrocresols in gaseous s
amples was proposed. The analytes from samples were absorbed in NaOH soluti
on. The alkaline solution was extracted with dichloromethane to remove the
neutral and basic interfering compounds. After acidification of the absorpt
ion solution the analytes were extracted into dichloromethane and analysed
by gas chromatography on capillary column with polydimethylsiloxane station
ary phase. Detection limits of individual analytes 0.1-1.4 mg m(-3) in gase
ous samples were achieved.
