PROBLEM TO BE SOLVED : To provide an adsorption separation material capable of selectively absorbing a rare-earth element, easy to operate a device and excellent in separation and collection capacity.
SOLUTION : An adsorption separation material is for selectively collecting a rare-earth element dissolved in aqueous solution. In the adsorption separation material, at least one diglycolamic type ligand expressed by a formula (2) is introduced into a polymer base material by graft polymerization. (In the formula (2), R represents a hydrogen atom, an alkyl group having 1-3 carbon atoms, an alkylene group having 1-3 carbon atoms, an acyl group having 1-2 carbon atoms or an aldehyde group, and * represents a bond.)
