Abstract

This study investigates the adsorption performance of rare earth elements by LanM (Lanmodulin) -doped zinc imidazolate framework-8 (ZIF-8). The results show that the LanM-doped ZIF-8 exhibits significantly higher adsorption capacity for rare earth elements compared to pure ZIF-8, along with high selectivity for various metal ions. Based on a series of characterizations indicate that the incorporation of LanM enhances the adsorption capacity of rare earth elements (Qmax = 787.93 mg/g, 25 °C) by changing pore structure, altering surface charge distribution, exposing more adsorption sites. Furthermore, Lanmodulin@Zinc Imidazolate Framework-8 (LanM@ZIF-8) shows rapid adsorption characteristics and reaches adsorption equilibrium within 1 h. This study provides new insights and theoretical support for the design of MOFs with high selectivity and adsorption capacity for rare earth elements.
