Capillary column gas chromatographic determination of nitro polycyclic aromatic compounds in particulate extracts
A method for the determination of nitro polycyclic aromatic compounds in particulate extracts was developed and applied to the analysis of a diesel exhaust extract. Silicic acid column chromatography combined with reduction of the nitro compounds with KBH/sub 4/ catalyzed with copper(II) chloride and derivatization with pentafluoropropionic anhydride yielded an enriched nitro fraction. Nitro polycyclic aromatic compounds present in this fraction as pentafluoropropyl amides were subsequently analyzed by capillary gas chromatography with electron capture, nitrogen-selective thermionic, and flame ionization detection and by gas chromatography/mass spectrometry. Ten nitro polycyclic aromatic compound isomers were positively identified based on comparisons of gas chromatographic retention data of standard compounds, gas chromatography/mass spectrometry, and low-resolution mass spectral data. Over 120 nitro polycyclic aromatic compounds were tentatively identified. 16 references, 4 figures, 2 tables.
