AB  - 2,4-dichlorophenol (2,4-DCP) is a typical chlorophenol that has been widely used 
      in industrial production and caused serious pollution to the environment. In this 
      study, the performance of Fe/Ni bimetallic nanoparticles supported on polystyrene 
      cation exchange resin (Fe/Ni-D072) to remove 2,4-DCP was evaluated. The effects 
      including the doping amount of Ni, the dosage of Fe/Ni-DCP, the initial 
      concentration of 2,4-DCP, and pH value of the solution on the removal efficiency 
      were also investigated. The results showed that when the initial concentration of 
      2,4-DCP was 20 mg/L and pH = 7.3, 90% of 2,4-DCP could be dechlorinated by 
      Fe/Ni-D072 (Ni% = 30 wt%, dosage: 6.7 g/L) after 12 h reaction. The 
      dechlorination process followed a pseudo-first-order model, and the reaction 
      constant was 0.252 h(-1). In addition, the effects of humic acid and common 
      coexisting ions on dechlorination were studied. The results showed that humic 
      acid with a low concentration (5 mg/L) and CO(3)(2-) restrained the degradation 
      of 2,4-DCP. The dechlorination products of 2,4-DCP were identified by HPLC and 
      the result showed phenol was the main product with a slight amount of 2-CP as the 
      dechlorination intermediate, and 4-CP was barely detected. These results suggest 
      that Fe/Ni-D072 was a promising catalytic material for the removal of 
      chlorophenol and has great application prospects in groundwater remediation.
