Abstract
MIL-88B(Fe)-NH2 material was prepared by a simple solvothermal method. Various techniques were performed to investigate material characteristics including X-ray diffraction (XRD), scanning electron spectroscopy (SEM), transmission electron microscopy (TEM) and Brunauer-Emmett-Teller (BET) surface area. The result indicates that the particle shape is a bipyramidal hexagonal prism having a porous surface, and the BET surface area is 13.43 m2/g. Adsorption of congo red (CR) onto MIL-88B(Fe)-NH2 was studied as well. The adsorption equilibrium of the material is reached rapidly after 10 minutes with excellent adsorption efficiency (98.02%). Adsorption kinetic conforms to Langmuir isothermal adsorption model with the high maximum capacity of 333.33 mg/g.
