AB  - ABSTRACTThe dechlorination of 2,4-dichlorophenol (2,4-DCP) by a nanoscale Fe/Ni 
      material was investigated at room temperature. 2,4-DCP can be removed more 
      quickly by an Fe/Ni material with 2% Ni. Fe/Ni exhibited excellent adsorption and 
      reduction efficiency toward 2,4-DCP in an aqueous solution over a wide range of 
      pH values. The removal rate of 2,4-DCP exceeded 95% in 60 min in the pH range of 
      3.0-9.0, and more than 75% was dechlorinated to phenol (CA). The degradation 
      pathway of 2,4-DCP was confirmed based on analysis of the intermediate and end 
      products. A portion of 2,4-DCP was first dechlorinated with a chlorine atom to 
      produce 2-chlorophenol and 4-chlorophenol, and then dechlorination was performed 
      sequentially to form CA. The other portion of 2,4-DCP was dechlorinated to remove 
      two chlorine atoms simultaneously to generate CA. The investigations are 
      essential to the application of iron-based remediation technology.
