| Abstract: | Adopts sol-gel method to prepare the P25/SnO2 compound catalyst, taking the photocatalytic degradation of reactive brilliant red X-3B as a model, to research several factors which influence the reaction. The results indicated that the degradation ratio of reactive brilliant red X-3B reach 95.8% within 60 minutes under the conditions that the amount of catalyst was 4 g/L, pH = 6, initial reactive brilliant red X-3B concentration was 40 mg/L and added 2 mL/L H2O2. The degradation kinetic of reactive brilliant red X-3B in the P25/SnO2 compound catalyst meet the first-order reaction. |
