Synthesis and Characterization of Lu(III) Ion Imprinted Polymer

A novel Lu(III) ion imprinted polymer (IIP) was synthesized by bulk polymerization using Lu(III) ion as a template, Lu(III)-4-vinylpyridine-acetylacetone complex as a functional monomer and ethylene glycol dimethacrylate as a crosslinker. The Lu(III) IIP was systematically characterized by adsorption test, UV-Vis spectrophotometry, FTIR spectroscopy, element analysis, X-ray diffraction, pore size analysis, SEM and TGA studies. The results showed that the maximum adsorption of Lu(III) IIP was 64.2 mg g(-1) with the adsorption equilibrium time of 30 min and the optimum pH was 5.5. The synthesized Lu(III) IIP had a good selective recognition ability for Lu(III) ion compared with other ions and possessed a favorable heat stability.
