content was in the range of 0.11-1.62% weight, and the dechlorination kinetics was
found to be linearly dependent on the Pd content (Fig. 4.5). The proposed dechlorination
mechanism includes H 2 activated in the form of Pd-H 2 (by adsorption) as a reductive
force to the aromatic ring of PCBs. Hydrogen gas was possibly generated by the
reaction of Mg with water (Agarwal et al., 2007).
