| Abstract: | This paper describes a method for separation and identification of azaarenes and nitro-PAH in sediment. Sample was subjected to a Soxhlet extraction by using dichloromethane, and then the extract was preseparated on a Sephadex LH-20 column eluted with isopropanol. The fraction containing azzarenes and nitro-PAH was analyzed by fused-silica capillary gas chromatography and GC/MS/DS. Some nitro?PAH standards were prepared in this laboratory. Ten standard azaarenes were obtained from Dr. Wekeham. 12 standards were investigated by EI-MS. Altogether, 25 azaarenes and nitro-PAH were detected on the basis of the standard mass spectra and mass chromatography. The tentative sources of this kind of compounds are also discussed. |
