The preparation of a lanthanum ion-imprinted polymer is described via surface ion imprinting, with polyethyleneimine as the functional monomer and SBA-15 as the matrix material. Its structure was characterized and analyzed, and static adsorption experiments were carried out to determine the best experimental conditions for the adsorption of lanthanum ions. The effects of initial concentration, temperature, adsorption time and pH on the adsorption of lanthanum ion surface-imprinted polymer were investigated. In addition, the regeneration performance of La(III)-IIP-PEI/SBA-15 on lanthanum ion was studied and showed that La(III)-IIP-PEI/SBA-15 has strong specific recognition ability and high reuse performance.
