Catalytic dechlorination of chlorobenzene in water by Pd/Fe bimetallic system.
Catalytic reductive dechlorination of monochlorobenzene(MCB) was carried out in the palladium/iron system. With low Pd loading (0.005%), 45% dechlorination efficiency was achieved within 5 h. Pd as catalyst accelerated the reductive dechlorination reaction. Dechlorination mechanism and kinetics were discussed. The reaction took place on the bimetal surface in a pseudo-first-order reaction, with the rate constant being 0.0071 min(-1) (K(SA) = 8.0 x 10(-3) L/(m2 x h)). The reduction product for MCB was benzene.
