Abstract:Aim at the problems that Fe/Ni and Fe/Pd bimetal are high cost and weak hydrophobicity,nanoscale Fe/Cu bimetal was modified and used to dechlorinate 2,4-dichlorophenol (2,4-DCP).The effects of mass ratio of copper (ω(Cu)) on the reduction of 2,4-dichlorophenol by Fe/Cu were investigated.The results showed that when the reaction time was 80 h,the removal rate of 2,4-DCP by Fe/Cu (ω(Cu)=10%) was nearly 100% and the intermediate,4-chlorophenol (4-CP),was converted into end product,phenol (CA).The yield of CA was found to reach to 91.8%.The dechlorination pathways of 2,4-DCP were confirrned,that is,2,4-DCP was dechlorinated a chlorine atom to produce 4-CP at first,and then the dechlorination was performed sequentially to form CA.2,4-DCP was dechlorinated two chlorine atoms simultaneously to generate CA.XRD analysis indicated that Fe0 was oxidized to Fe3O4 and Fe2O3 and Cu0 was oxidized to CuO after the reaction.
