AB  - The transformation of halogenated organics in advanced oxidation processes (AOPs) 
      has been extensively investigated. However, we currently know little about the 
      fate of halogenated pollutants in the presence of exogenic halides (Cl(-) or 
      Br(-)). Herein, the degradability, mineralization rate, and accumulation capacity 
      of adsorbable organic halogen (AOX) for chlorophenols (2-chlorophenol (2-CP), 
      3-chlorophenol (3-CP), 4-chlorophenol (4-CP), and 2,4,6-trichlorophenol (TCP)) 
      were compared in the Fe(2+)/persulfate (PS) process with the addition of exogenic 
      halides. Results indicate that exogenic X(-) can lead to a decrease in 
      chlorophenols degradation and mineralization rate, undesirable accumulation of 
      AOX, and generation of halogenated by-products which are more toxic than 
      precursor chlorophenols. Results of kinetics modeling show that Cl(2)(*-) plays 
      more important role than SO(4)(*-) with an addition of Cl(-), while SO(4)(*-), 
      Br(2)(*-), and Br(2) are responsible for the effect of Br(-). As well, the effect 
      of endogenic chlorine atoms on chlorophenols reveals that the degradability and 
      AOX formation potential of 3-CP are highest while that of TCP are the lowest. 
      This study demonstrates the significant influence of endogenic chlorine atoms and 
      exogenic X(-) on the fate of typical organic halogen compounds. Consequently, the 
      X(-) level and position/number of halogen atoms should be considered 
      simultaneously when treating organohalogen compounds.
