AB  - The cobalt ferrite-reduced oxidized graphene (CoFe(2)O(4)/rGO) catalyst was 
      synthesized by hydrothermal method and characterized by Powder X-ray diffraction 
      (XRD), X-ray photoelectron spectroscopy (XPS), Scanning electron microscope 
      (SEM), Brunauere Emmette Teller (BET) and Hysteresis loop. For developing a new 
      method of removing elemental mercury (Hg(0)) from flue gas, the effects of 
      catalyst dosage, PMS concentration, solution pH and reaction temperature on the 
      removal efficiency were investigated experimentally by using peroxymonosulfate 
      (PMS) catalyzed by CoFe(2)O(4)/rGO at a self-made bubbling reactor. The average 
      removal efficiency of Hg(0) in a 30-min period reached 95.56%, when 
      CoFe(2)O(4)/rGO dosage was 0.288 g/L, PMS concentration was 3.5 mmol/L, solution 
      pH was 5.5 and reaction temperature was 55  degrees C. Meanwhile, based on the free 
      radical quenching experiments, in which, ethyl alcohol and tert butyl alcohol 
      were used as quenchers to prove indirectly the presence of (*)OH and SO(4)(*-), 
      the characterizations of catalysts and reaction products, and the existing 
      results from other scholars. The reaction mechanism was proposed.
