- Abstract:
- Co-Mn/γ-Al2O3 composite catalyst was prepared with γ-Al2O3 as support and manganese oxide and cobalt oxide as active components. The catalyst was characterized by XRD and SEM, and the effects of ozone dosage, initial pH of solution and catalyst dosage on the removal rate of COD in aniline wastewater were investigated. The main active components of the catalyst were MnO2 and Co3O4, which were uniformly loaded on the surface of alumina particles. When the dosage of ozone was 0.6 g/L, the pH of solution was 8, and the dosage of catalyst was 5 g/L, the removal rate of COD in aniline wastewater catalyzed by ozone was 84.79%. In the repeated experiments, the COD removal rate was stabilized in the range of 82.15%-84.79%, indicating that the catalyst had good stability.
