Chemical detoxification of polychlorinated biphenyls (PCBs)
The present invention relates to the chemical detoxification of polychlorinated biphenyls by converting them to non-hazardous substances. In particular, the invention relates to chemically destroying polychlorinated biphenyls on site for decontamination purposes without creating pollution or hazardous situations. The invention provides a two-step process where polychlorinated biphenyls (PCBs), i.e. biphenyl having 2 to 10 chlorine atoms, are first reduced to unsubstituted biphenyl, then oxidized to a biodegradable dicarboxylic acid having the formula: (CH/sub 2/)n (CO/sub 2/H)/sub 2/, where n=O to 10 possible -CH2- units for application in aqueous systems including water, mud and wet soil.
