Composite materials MIL-53(Fe)/Fe3O4 have been successfully synthesized on the basis of MIL-53 metal organic framework materials by hydrothermal method. Material characteristics were studied through XRD, SEM methods. The material has good adsorption capacity of the Congo Red pigment. The Congo Red adsorption activity of the composite material was investigated. The results showed that the adsorption efficiency of Congo Red of MIL-53(Fe)/Fe3O4 reached 98.89% after only 5 minutes, with the concentration of 2.227 mg/l in Congo red solution. The Congo Red adsorption process of MIL-53 (Fe)/Fe3O4 follows the Freundlich isothermal adsorption model.
