Catalytic reduction of chlorinated and recalcitrant compounds in contaminated water

Catalysis dechlorination of chlorinated organic matter by palladium/iron bimetallic particles represents one of the latest innovative technologies for contaminated soil and groundwater remediation. The reaction of dechlorination is believed to take place on the surface site of the catalyst in a pseudo-first-order mode. The dechlorination rate increases with an increase of the bulk loading of palladium due to the increase of both the surface loading of palladium and the total surface area exposed. The results show that no other intermediates were generated besides Cl−, benzene and chlorobenzene during dechlorination of o-dichlorobenzene.
