Efficiency and Kinetics of Catalytic Ozonation of Acid Red B over Cu-Mn/γ-Al₂O₃ Catalysts

Abstract

The efficiency and kinetics of catalytic ozonation of Acid Red B over Cu-Mn/γ-Al₂O₃ catalysts were investigated. Cu-Mn/γ-Al₂O₃ catalysts were prepared by impregnation and characterized by X-ray diffraction and X-ray fluorescence. The removal efficiencies of Acid Red B and total organic carbon were up to 99.35% and 54.38%, respectively. The Cu-Mn/γ-Al₂O₃ catalysts were stable and easy to be reused. The interim products were analyzed by means of Vis-UV absorption spectrum. Cu-Mn/γ-Al₂O₃ catalytic ozonation of Acid Red B conformed to the pseudo–first-order kinetics reaction model.
