Title
The influence of ion effects on the Pd-catalyzed hydrodechlorination of 4-chlorophenol in aqueous solutions
Abstract

The aim of this work was to study the influence of ions on the hydrodechlorination of 4-chlorophenol in water over 5% Pd/C catalyst. It was found that the presence of some ions such as Na+, K+, NH4+, Ca2+, Mg2+, Cl−, Br−, CO32-, HCO3-, SO42- and NO3-etc., did not show negative effects on catalyst activity in the hydrogenation process of 4-chlorophenol in aqueous solutions. But, when Fe2+, Fe3+, Cu2+, Zn2+, Ni2+ and Pb2+etc., were present in water, they could reduce the activity of Pd/C and even led Pd/C to deactivate.
