| Abstract | BIOSIS COPYRIGHT: BIOL ABS. Supercritical fluid ectraction (SFE) proven to be an attractive alternative to solvent extraction of PCBs and petroleum hydrocarbons (PHCs) from contaminated soils. This paper discusses the effects of a number Of parameters (pressure, temperature and modifier) on the SFE of PCBs and of the saturated (HCSs) and aromatic (PAHs) fractions which make up a crude oil as determined by Using CO2 as supercritical fluid. The experiments were carried out by spiking two different soils, composed by clay and clay-sand, with Aroclor 1254 (PCBs = 0.38 mug/gsoil) and saturated (HCSs = 0.02 g/gsoil) and aromatic (PAHs = 0.1 g/gsoil) fractions from crude Oil. CO2 modified by acetone yielded high recoveries of both PCBs (>95%) and polycyclic aromatic hydrocarbons (PAHs) (100%). Lower recoveries were observed for the aliphatic compounds due to the increase of the solvent polarity following on the addition of acetone to the supercritical fluid. In particular this paper shows that the li |
