Lanthanides adsorption on metal-organic framework: Experimental insight and spectroscopic evidence

On membrane-based approaches for rare earths separation and extraction – Recent developments

“…MOFs have shown tremendous potential for the separation of REEs due to their intrinsic properties e.g., large surface area, tunable pore size, tunable surface chemistry, and unsaturated metal sites [233,234]. Paz et al [235] synthesized Cu-BTC MOF via the solvothermal reaction for the adsorption of Samarium (Sm), From the kinetic adsorption study, it was found that the pseudo-first-order kinetics well described the adsorption kinetics and more than 97% of La(III) ions were adsorbed onto the prepared MOF. In the fixed bed column mode, the dynamic adsorption capacity of La(III) ions onto the synthesized MOF was 20% higher than that from the batch experiments.…”
