  ABSTRACT: The chemically modified polymeric adsorbents were evaluated for selective solid-phase extraction of polycyclic aromatic hydrocarbons. Commercially available Amberlite XAD-2 and XAD-4 resins were modified with macrocyclic protoporphyrin IX or tetrakis(p-carboxyphenyl)-porphyrin through the ketone linkage. The variables that influence the selectivity and recovery of the solid-phase extraction were optimized. The best result was obtained with XAD-4 resins modified with macrocyclic protoporphyrin IX. After preconcentration and clean-up step, the polycyclic aromatic hydrocarbons were determined by gas chromatography with mass spectrometric detection. The method was used to determine polycyclic cromatic hydrocarbons in soil, and the recovery was in the range of 79.6% to 94.1%.
