RARE EARTH ADSORBENT AND RARE EARTH ADSORPTION METHOD USING THE SAME

摘要

A rare earth adsorbent of an embodiment has a chelidonic acid monoamide group as a ligand, and contains a functional group represented by the following general formula (1):;wherein: X is selected from hydrogen or an alkali metal; R1 is a bonding group with a simple polymer; and R2 is a functional group selected from hydrogen, an alkyl group, an alkenyl group, an alkynyl group, and an aryl group, and may be substituted by nitrogen or oxygen or contain a functional group containing the atoms in a side chain.
