Chemical detoxification of polychlorinated biphenyls (PCBS)

摘要

The invention provides a two-step process where polychlorinated biphenyls CBs), 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).sub.n (CO. sub.2 H).sub.2, where n=0 to 10 possible --CH.sub.2 --units for application in aqueous systems including water, mud and wet soil.
