ZERO-VALENT METALLIC TREATMENT SYSTEM AND ITS APPLICATON FOR REMOVAL AND REMEDIATION OF POLYCHLORINATED BIPHENYLS

摘要

PCBs are removed from contaminated media using a treatment system including zero-valent metal particles and an organic hydrogen donating solvent. The treatment system may include a weak acid in order to eliminate the need for a coating of catalytic noble metal on the zero-valent metal particles. If catalyzed zero-valent metal particles are used, the treatment system may include an organic hydrogen donating solvent that is a non-water solvent. The treatment system may be provided as a“paste-like”system that is preferably applied to natural media and ex-situ structures to eliminate PCBs.
