AB  - The electrochemically reductive dechlorination of 2,4-dichlorophenol (2,4-DCP) in 
      aqueous solution on palladium/polymeric pyrrole-cetyl trimethyl ammonium 
      bromide/foam-nickel electrode (Pd/PPy-CTAB/foam-Ni electrode) was investigated in 
      this paper. Pd/PPy-CTAB/foam-Ni electrode was prepared and characterized by 
      cyclic voltammetry (CV), scanning electron microscope (SEM), X-ray diffraction 
      (XRD), Brunauer-Emmett-Teller (BET) adsorption and inductively coupled 
      plasma-atomic emission spectroscopy (ICP-AES). The influences of some 
      experimental factors such as the dechlorination current, dechlorination time and 
      the initial pH on the removal efficiency and the current efficiency of 2,4-DCP 
      dechlorination on Pd/PPy-CTAB/foam-Ni electrode were studied. Complete removal of 
      2,4-DCP was achieved and the current efficiency of 47.4% could be obtained under 
      the conditions of the initial pH of 2.2, the dechlorination current of 5 mA and 
      the dechlorination time of 50 min when the initial 2,4-DCP concentration was 100 
      mg L(-1). The analysis of high performance liquid chromatography (HPLC) 
      identified that the intermediate products were 2-chlorophenol (2-CP) and 
      4-chlorophenol (4-CP). The final products were mainly phenol. Its further 
      reduction product cyclohexanone was also detected. The electrocatalytic 
      dechlorination pathways of 2,4-DCP on Pd/PPy-CTAB/foam-Ni electrode were 
      discussed. The stability of the electrode was favorable that it could keep 
      dechlorination efficiency at 100% after having been reused 10 times. Results 
      revealed that the stable prepared Pd/PPy-CTAB/foam-Ni electrode presented a good 
      application prospect in dechlorination process with high effectiveness and low 
      cost.
