Chemical detoxification of polychlorinated biphenyls (PCBS)

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: (CH2)n (CO2H)2, where n=0 to 10 possible -CH2-units for a...

Zusammenfassung:	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: (CH2)n (CO2H)2, where n=0 to 10 possible -CH2-units for application in aqueous systems including water, mud and wet soil.
