AB  - The coupling of electrolysis and the peroxydisulfate (PDS) activation was 
      selected in this study to degrade solution-phase 2,4,6-trichlorophenol (TCP). To 
      enhance the PDS activation efficiency and catalytic recycling ratio, a novel 
      magnetic activator, nano iron coated on neodymium iron boron/activated carbon 
      nanocomposite (Nano-Fe@NdFeB/AC), was synthesized and utilized as catalytic 
      particle electrodes. To increase the mass transfer ability, a novel magnetic 
      internal circulation electrolytic reactor (MICE) was established. The results 
      indicated that globular Fe, with sizes ranging from 25 nm to 300 nm, is present 
      on the surface of the catalyst. This catalyst has sufficient magnetism to be 
      separated by the magnetic separation method and its specific saturation 
      magnetization and residual magnetization were 1.48 and 0.26 emu/g, respectively. 
      At the optimal condition of [pH](0 )= 9.0, [Na(2)S(2)O(8)](0 )= 2.0 mmol/L, 
      [Nano-Fe@NdFeB/AC](0 )= 5.0 g/L and I = 50 mA, the TOC percentage of removal 
      could reach 84% after 30 min of reaction. The TCP mineralization follows 
      pseudo-first-order kinetics. The intermediate products of 
      2,6-dichloro-2,5-cyclohexadiene-1,4-dione, Tetrachloro-hydroquinone, and 
      2,3,5,6-tetrachloro-p-benzoquinone were found during the reaction. TCP 
      mineralization was confirmed to have a hybrid mechanism involving reductive 
      dechlorination with Fe, *OH addition oxidation and electron capture by SO*(4) 
      (-). This study provides a new method for the treatment of degradation-resistant 
      pollutants.
