Abstract
. We leveraged the selectivity of HEW5 in a 7 mL column to demonstrate a single-stage, chelator-free separation of an equimolar lanthanum-neodymium mixture, achieving a high purity (>90%) and yield (90%) of REEs. Additionally, immobilized HEW5 was used to remove non-REE ions from a simulated leachate stream and separate lanthanum (>90% purity) from other REEs in a single separation stage.
