ABSTRACT:
Hydrophobic contaminants are removed from a particulate matter by contacting the particulate matter with a solid organic phase. The hydrophobic contaminants have greater affinity for the solid organic phase than for the particulate matter and repartition to the solid organic phase. The solid organic phase is then separated from the particulate matter. A typical embodiment utilizes polystyrene particles to remove polychlorinated biphenyls from soil.
