AB  - In this study, coal fly ash supported MnO(2) (CFA@MnO(2)) was synthesized as 
      heterocatalyst for the activation of peroxymonosulfate to degrade Acid Red 73 
      (AR73). The synthesized catalyst was characterized by X-Ray Fluorescence 
      Spectrometer (XRF), X-ray powder diffraction (XRD), Scanning electron microscope 
      (SEM), X-ray photoelectron spectroscopy (XPS) and Brunauer-Emmett-Teller (BET). 
      The composite of CFA@MnO(2) possesses a large surface area of 74.59 m(2)/g. In 
      the catalytic experiment, CFA@MnO(2) exhibits excellent catalytic performance 
      with 99.13% AR73 removed within 40 min with a high kinetic rate constant of 
      0.124 min(-1), 5.49 times higher than that of pure MnO(2). The operating 
      parameters of CFA@MnO(2)-based fenton catalytic system were discussed, including 
      MnO(2) loading, solution pH, PMS dosage and temperature. The catalyst maintained 
      a relatively high removal rate (>85%) over 5 cycles and degradation intermediates 
      are detected on the catalyst surface after cycled via XPS analysis. The 
      degradation mechanism was investigated by quenching experiments and Electron 
      Paramagnetic Resonance technology. The surface-bound (.)OH and SO(4) (.-) are 
      considered as the main active radicals in the degradation process. The composite 
      of CFA@MnO(2) provides a low-cost and efficient alternative for the catalytic 
      oxidation of organic pollutants.
