dc.description.abstract | Under the oxic condition, the most effective removal of pentachlorophenol (PCP) with Pd/Fe nanoparticles (NPs) is demonstrated as compared to the anoxic condition. Concurrent oxidation and reduction of polychlorinated compounds such as PCP by zerovalent Pd/Fe were first observed. The optimal Pd content of the bimetallic NPs is only around 0.54mgg-1 Fe. Increases in both dosage of Pd/Fe NPs and temperature enhance degradation rates and efficiency. The activation energy of 29kJ/mol indicates that the degradation is a surface-mediated mechanism. The removal mechanism also includes adsorption, which explains that the dechlorination of Cl on PCP molecules at ortho and meta positions is easier than that at para position. Overall, Pd/Fe NPs can apply directly to degrade polyhalogenated compounds in water without deaeration. © 2015 Elsevier B.V. | - |
