Abstract
In the extraction of spiked PCB from soil, three extracting fluids were inv estigated: supercritical carbon dioxide (CO2), supercritical sulfur hexaflu oride (SF6) and subcritical water. Among the tested fluids SF6 appeared to be appropriate especially for the extraction of low polar PCB. CO2 and wate r were found to be suitable for the quantitative extraction of all PCB. Wat er was judged as the best because of its low price, good availability and e nvironmental safety.
