Abstract

The loose and porous cobalt-cerium complex oxides were prepared by sol-gel method with high specific surface area and larger pore volume. The catalytic degradation effect of the prepared cobalt-cerium composite oxides on 2,4,6-trichlorophenol as model compound in the wastewater has been studied. The results showed that the cobalt-cerium composite oxides have good degradation activity on 2,4,6-trichlorophenol, because of redox ability and synergistic catalysis of cobalt-cerium composite oxides. The initial pH value of the solution was proven to have significant effect on the degradation, lower pH of the solution brought high degradation efficiency. 100 mg of cobalt-cerium composite oxide and 10 mL of 100 mg/L 2,4,6-trichlorophenol were vibrated at 25℃ for 30 h, the degradation efficiency of 2,4,6-trichlorophenol can reach 86.3%,and the amounts of the organic compounds apt to be oxidized decreased by 36.7%.
