摘要：

The dimethylformamide extracts from sewage sludges from a chosen sewage - treatment plant in highly industrialized region of Poland were investigated. Using the column chromatography with Al2O3 and silicic acid as the stationary phases, the fraction of azaarenes has been separated. GC-MS analysis of azaarenes fraction made it possible to identify 10 azaarenes and several of their alkyl derivatives, which dominate in the organic matter extracted from sewage sludges. The silicic acid column chromatography in connection with the reduction of nitroarenes and derivatization with pentafluoropropionic acid anhydride yielded an enriched nitrofraction. Nitroarenes present in this fraction as amide derivatives were also analysed by GC-MS method. There was found presence of 3 nitroarenes and their methyl derivatives.
