| Outline of Final Research Achievements |
Chelating resins for selective and rapid separation of critical metals, such as noble metals, rare earth elements, and rare metals, were prepared. As functional groups, polymer ligands, such as N-acetylated (Ac-), phosphomethylated (PM-), and carboxymethylated (CM-) polyethyleneimines (PEI), were immobilized on porous polymer resins. The resins immobilizing Ac-PEI and PM-PEI were useful for adsorption of noble metals (especially Au(III)) and rare earth elements, respectively. The resin immobilizing CM-PEI had the most excellent ability from the viewpoints of both selectivity and rapidity.
