KBrO₃ Catalyzed Wet Air Oxidation of C.I. Reactive Brilliant Red K-2G

Abstract:

The effect of KBrO₃ on catalytic wet air oxidation to be used in azo dye C.I. Reactive Brilliant Red K-2G decolorization under different conditions is evaluated. The reaction temperature, oxygen partial pressure, pH and catalyst dosage were studied. The optimal conditions of applying KBrO3/O₂ system were: reaction temperature 150°C, oxygen partial pre_{Subscript text}ssure 1.0 Mpa, pH 4 and Reactive Brilliant Red K-2G: KBrO₃ (mole ratio) 1:0.5. Under the optimal conditions, the color removal rate was 98.9%. KBrO₃/O₂ system was efficient in azo dye Reactive Brilliant Red K-2G decolorrization.
