AB  - This study describes a comparative degradation of various chlorophenols by 
      electro-Fenton method. Chloride released and reaction intermediate products were 
      determined by ionic chromatography (IC) and gas chromatography/mass spectrometry 
      (GC/MS). Using pentachlorophenol (PCP) as the model compound, we investigated the 
      effects of cell voltage, electrolyte concentration and pH to optimize the 
      degradation conditions. It was noted that the addition of small quantities of 
      Fe3+ or Fe2+ significantly accelerated the degradation rate. Under the optimal 
      conditions, electro-Fenton method was used to treat various chlorophenols 
      including PCP, 4-chlorophenol (4-CP), 2,4-dichlorophenol (2,4-DCP), 
      2,4,6-trichlorophenol (2,4,6-TCP) and their mixture aqueous solutions. Their 
      pseudo first-order degradation rate constants at the first stages were calculated 
      and compared, which gave the following sequence: 2,4-DCP>2,4,6-TCP>PCP>4-CP. The 
      relationship between the chlorine content and degradation rate was discussed and 
      compared with other advanced oxidation processes. Finally, we proposed the 
      degradation pathways of different chlorophenols.
