Adsorption and recognition properties of ionic imprinted polyamine IIP‐PEI/SiO2 towards Pb2+ ion

“…[5][6][7][8] Molecular imprinting is a powerful technique for preparing polymeric materials with artificial receptor-like binding sites for various substances, [9][10][11][12] and the molecular imprinted polymers (MIPs) have been used as materials of molecular recognition in many scientific and technical fields, such as solid-phase extraction, chromatograph separation, membrane separations, sensors, drug releases, and catalysts, etc. [13][14][15][16] In this article, we used an advanced surface imprinting technique, prepared ionic imprinted polymer IIP-PEI/SiO 2 on the surface of silica gel particles. The adsorption and recognition properties of IIP-PEI/SiO 2 for Pb 2þ were studied profoundly using batch rebinding method.…”
