AB  - The present study investigated the impacts of water matrix constituents 
      (CO(3)(2-), HCO(3)(-), Cl(-), Br(-), PO(4)(3-), HPO(4)(2-), H(2)PO(4)(-), 
      NO(3)(-), SO(4)(2-) and natural organic matters (NOM) on the oxidation of a 
      mixture of benzene, toluene, ethylbenzene, and xylenes (BTEX) by thermally 
      activated persulfate (PS). In the absence of matrix constituents, the BTEX 
      oxidation rates decreased in the following order: 
      xylenes > toluene  approximately  ethylbenzene > benzene. HCO(3)(-)/CO(3)(2-) and NOM inhibited 
      the BTEX oxidation and the inhibiting effects became more pronounced as the 
      HCO(3)(-)/CO(3)(2-)/NOM concentration increased. SO(4)(2-), NO(3)(-), PO(4)(3-) 
      and H(2)PO(4)(-) did not affect the BTEX oxidation while HPO(4)(2-) slightly 
      inhibited the reaction. The impacts of Cl(-) and Br(-) were complex. Cl(-) 
      inhibited the benzene oxidation while 100 mM and 500 mM of Cl(-) promoted the 
      oxidation of m-xylene and p-xylene. Br(-) completely suppressed the benzene 
      oxidation while 500 mM of Br(-) strongly promoted the oxidation of xylenes. 
      Detailed explanations on the influence of each matrix constituent were discussed. 
      In addition, various halogenated degradation byproducts were detected in the 
      treatments containing Cl(-) and Br(-). Overall, this study indicates that some 
      matrix constituents such as NOM, HCO(3)(-), CO(3)(2-), H(2)PO(4)(-), Cl(-) and 
      Br(-) may reduce the BTEX removal efficiency of sulfate radical-based advanced 
      oxidation process (SR-AOP) and the presence of Cl(-) and Br(-) may even lead to 
      the formation of toxic halogenated byproducts.
