Copper (II) ion-imprinted porous polymer microparticles with an average diameter of 250 m were prepared using 2 functional monomers, MAA and VP. The surface area of the particles was enlarged via pore formation (BET 60 m2/g) using a toluene porogenic agent. The adsorption properties of the Cu(II)-MIP showed a high affinity for Cu2+ over NI(II) and Zn(II) ions through batch and column analysis. The adsorption capacity of the prepared MIP was slightly lower than those from commercial sources, but the selective separation capability for the template Cu(II) ion was much higher than those from commercial sources. From this equilibrium adsorption behavior, the maximum capacity of the copper-imprinted polymer beads was 235 mol/g polymer. The selectivity coefficient for the copper ion was 42.48 times that of Zn, and 43.48 times that of Ni, respectively, with the present imprinted polymers having a copper selectivity at least 10 times higher than those from commercial sources. |
