Radiolabeled hexachlorocyclohexane, hexachlorobiphenyl, anthracene, and Parathion, representing the chemical classes of chlorinated hydrocarbons, chlorinated aromatic compounds polynuclear aromatic compounds, and organophosphate pesticides, respectively, were used to demonstrate the ability of supercritical carbon dioxide to desorb such environmentally significant compounds from the polymeric sorbent Tenax-GC. All compounds were recovered in excess of 90%. The recoveries of these compounds were examined as a function of the volume of carbon dioxide used for the desorption. The identities of the desorbed compounds were verified by the use of thin-layer chromatography and mass spectrometry. These results were compared to thermal desorption from Tenax for the same compounds where hexachlorobiphenyl and Parathion were recovered at only about 13%.
