Polychlorinated Biphenyls (PCBs) have been widely used to flame-retard products common in homes and theworkplace, and subsequently. Polychlorinated biphenyls (PCBs) typify a class of highly toxic, stable aromaticpollutants. PCBs are recently being scrutinized for potential environment damage in groundwater and in theatmosphere. The elimination of chemical pollutants from a contaminated environm...

Granular activated carbon (GAC), in the presence of dilute aqueous hypochlorite solutions typical of those used in water treatment, was converted to a reagent capable of carrying out free-radical coupling reactions and other oxidations of dilute aqueous solutions of phenols. The products included biphenyls with chlorine and hydroxyl substitution (hydroxylated polychlorinated biphenyls). For exa...
