Lanthanides are especially difficult to separate from each other due to their similar chemical behavior. However, ensuring high elemental purity is necessary for most industrial applications. 1,10-phenanthroline carboxamide compounds showed good results towards selective lanthanide separation in nitric acid medium. Here, we report the change in selectivity that occurs when modifying the counterion.
