A natural Protein for Selective and Efficient Extraction of Rare-Earth Elements


This work demonstrates that Lanmodulin (LanM) is the most selective macromolecule for rare-earth elements (REEs) characterized to date and outperforms many synthetic REE chelators. LanM exhibits extreme affinity for the REEs, remains bound to them down to pH 2.5, and withstands high temperatures and molar amounts of competing non-REE metal ions. The suitability of LanM-based systems for extracting REEs from complex matrices, such as E-waste and precombustion coal leachates, is also demonstrated.
