"One-pot" preparation and adsorption performance of chitosan-based La/Y dual-ion-imprinted thermosensitive hydrogel.

Temperature-sensitive materials are increasingly of deep interest to researchers. Ion imprinting technology is widely used in the field of metal recovery. In order to solve the problem of rare earth metal recovery, we designed a temperature-sensitive dual-imprinted hydrogel adsorption product (CDIH) with chitosan as the matrix, N-isopropylacrylamide as a thermally responsive monomer, and La and Y as the co-templates.
