Synthesis of MnO2 Nanoparticles Catalyst and Application to Treatment of Organic Compounds in Agricultural Processing Villages- a Case Study in Duong Lieu Village, Ha Noi Capital, Viet Nam
- Nguyen Thi Hong Hanh
- MnO2 exhibits excellent catalysis properties. In this work, nano MnO2 catalysts were synthesized from manganese sulfate and potassium permanganate by the co-precipitation method at room temperature. The characterization of the product was performed by Brunauer-Emmett-Teller (BET), X-ray diffraction (XRD), energy dispersive analysis of X-rays (EDX), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The results showed that this material had a small particle size about 0.5 µm and surface area about 113.0601 m2/g. The wastewater samples taken from Duong Lieu Agricultural Processing Village after wastewater treatment system were treated with nano MnO2 catalysts in the laboratory. The results showed that the ozonation with nano MnO2 catalyst occurred rapidly than ozonation reaction without catalyst. In these treatment, the catalytic ozonation with 0.02 g/l could reduce the COD demand from 3814.27 mg/l to 66.14 mg/l with 98.27% efficiency. Therefore, the ozonation with nano MnO2 catalysts can be considered as an effective and feasible means for treating the organic compounds in wastewater
