ABSTRACT
Zero valent metals (ZVMs) recently have received a lot of attention as media for permeable reactive barrier. A reductive degradation study for dichlorinated model compounds were conducted. It is known that halogenated aromatic compounds slowly degraded with plain ZVMs. To overcome the low reactivity of plain ZVMs, palladium was used as catalyst. Palladium coated zinc (Pd/Zn) was tested for the three dichlorobiphenyls. Pd/Zn degraded the target compounds rapidly and monochlorobiphenyls and biphenyl were detected as daughter compounds. The produced monochlorophenyl also gradually degraded and biphenyl was the final product. The reaction rate among the three compounds were in order of 3,4-DCBP> 2,4-DCBP > 2,3-DCBP. The degradation rate was proportional to the metal dose. The degradation pathway was mainly step-by-step dechlorination.
