AB  - Mineral-catalyzed Fenton-like system has been found to be effective for the 
      discoloration of dyeing wastewater. In our present study, schorl has been 
      successfully developed as a novel heterogeneous catalyst for discoloration of an 
      active commercial dye, Argazol blue (BF-BR), in an aqueous solution. Through a 
      number of batch discoloration experiments under various conditions, it was found 
      that the reactivity of the system increased by, respectively, increasing schorl 
      dosage, temperature, hydrogen peroxide starting concentration and by decreasing 
      the pH. At the condition of pH 2, T=55 degrees C, [BF-BR](0)=200mg/L, 
      [H(2)O(2)](0)=48.5 mmol/L and schorl dosage=10 g/L, 100% of discoloration ratio 
      can be achieved in less than 4 min, and 72% of total organic carbon (TOC) can be 
      removed in less than 200 min. The reaction kinetics analysis shows that the 
      discoloration of BF-BR follows the first-order kinetics. The schorl samples after 
      BF-BR discoloration was tested by X-ray diffraction (XRD), Fourier transform 
      infrared spectroscopy (FT-IR), and Scanning electron microscope (SEM) and the 
      results rule out the possibility of formation of new solid phases during BF-BR 
      discoloration. The content of Fe ion leaching in the solution was also measured 
      using inductively coupling plasma-atomic emission spectra (ICP-AES). A mechanism 
      proposed herein indicates adsorption and Fenton-like reaction (heterogeneous and 
      homogeneous) are responsible for the discoloration of BF-BR.
