Catalytic Degradation of Azo Dye Congo Red in Aqueous Solution by LiMn₂O₄

Abstract:

Catalytic degradation of azo dye Congo red in aqueous solution by spinel LiMn2O4 was studied. Degradation conditions were also optimized by orthogonal experiment. The results showe that the optimal degradation experimental conditions are: The initial pH is 3.0; The amount of catalyst is 10.0 mg; The amount of 30% H2O2 is 2.00 mL. The decolourization ratio of 20 mL 20 mg/L Congo red solution is 85.95%.
