Abstract
In this study, functionalized MIL-101(Cr) with amine group (ED-MIL-101(Cr)) was Synthesized. Using grafted MOF, adsorption experiments of Cu(II) and Cd(II) ions in single and binary solutions were performed. The adsorption results were fitted well by the Langmuir and extended Freundlich models for single ion and binary ion solutions, respectively. Data revealed that ED-MIL-101(Cr) possess maximum adsorption capacities (mg/g) of 69.9 and 63.15 for Cu(II) and Cd(II), respectively,with affinity order Cu(II) ˃ Cd(II) in binary ion solution. The kinetic data was well described by the pseudo-second-order model. The amino-functionalized MIL-101(Cr) can be a promising candidate for metal ion removal from the aqueous environment.
