Molecular imprinted polymers (MIPs) are a type of supramolecular compounds with potential application in medicine, environment, materials science, etc. Here we presented our preliminary results of our proposal of the bulk polymerization using Er+3 and Cu+2 as the templates, vinyl benzoic acid (VBA) and phenanthroline (fen) as the functional monomers in order to form a coordination complexes: [Cu(VBA)2fenH2O] and [Er2(VBA)6fen2]. Subsequently it was added ethylene glycol dimethylacrylate (EGDMA) as a crosslinker, 2,2-azo-bis-isobutyronitrile as an initiator (AIBN) and nitromethane as a solvent porogen, to obtain a copolymer and then the corresponding MIP. The synthesized copolymer with copper and NIP (non-imprinted polymer) were characterized by spectroscopy, thermogravimetric analysis and microscopy. The FTIR characterization showed a broad C=O stretching peak at 1589 cm-1 and 1718 cm-1 for copolymer and NIP from VBA and EGDMA, C-CH3 stretching peak at 1257 cm-1 due to the presence of tertbutyl group in AIBN. The copolymer and NIP are nonsoluble in water, polar solvents as main feature of polymers. In conclusion, we are focused on the synthesis of MIPs and its application for selective extraction of metal ions in polluted water, with similar characteristics to Er+3 and Cu+2 as ionic radius, electronegativity, electronic configuration and geometry.
