Abstract:
Chroma of dyeing wastewater is large, and photocatalytic degradation system is limited by poor permeability. In allusion to these problems, MgFe2O4 was prepared by chemical co-precipitation method. MgFe 2O4 structure was characterized by FT-IR, XRD and nanometer The catalytic effect of MgFe 2O4 on decoloring the reactive dyes H 2O2 under microwave was investigated. Based on single factor experiment design, the influences of MgFe 2O4 mass concentration, H 2O2 volume fraction, microwave power and response time on decoloring rate of simulated dye waste water were studied in combination of response surface analysis. The results show that, the catalyst can make decoloring rate of 200 mg/L reactive dyeing wastewater approach 100% under the following conditions: MgFe2O4 mass concentration 4.5 g/L, H 2O2 volume fraction 6.2 mL/L, microwave power 281.58 W and response time 7.86 min. Besides, the catalyst can be recycled and reused by magnetic force.
