Abstract

A reversed phase thin-layer chromatographic method employing the chemically bonded octadecylsilane as the stationary phase (Whatman KC18), has been investigated for the simultaneous analysis of polycyclic aromatic hydrocarbons (PAH) and nitrogen heterocyclics (aza-arenes). Separations of mixtures of reference compounds were obtained with a number of mobile phases (developers) and the separation efficiencies depending on the individual solvent components were summarized. Double development and twodimensional thin-layer chromatography were used for identification purposes involving several environmental samples. This method, coupled with selective excitation fluorescence spectrometry, proved to be effective for the quantitative measurements of selected PAH and aza-arene compounds. The analytical procedures for environmental samples generally consisted of liquid-liquid partion, fractional purification by gel permeation and adsorption chromatography, and separation of the extract into its various components by reversed phase thin-layer chromatography. Because of its simplicity and speed, the method shows promise for the routine screening of PAH and aza-arenes in environmental samples with very little investment in equipment and materials.
