| Abstract: | Mn/Ce complex oxide catalysts for catalytic wet air oxidation of high concentration phenol wastewater treatment were prepared by coprecipitation. The catalyst preparation conditions were optimized by orthogonal layout method and single-factor experimental analysis. The Mn/Ce serial catalysts were characterized and metal cation leaching conditions were measured. The results show that the catalysts have the characters of high catalytic activities and low metal cation leaching in wastewater treatment by CWAO. The new catalysts would have a promising application in high concentration organic wastewater treatment by CWAO. |
