Abstract:

 In this study, ion-imprinted polymers were prepared. These polymers can be used for the selective removal of CuII ions from aqueous solutions. To this end, E-2-hydroxy-5-vinylphenyldiazonyl benzaldehyde was used as a functional monomer in the synthesis stage of the polymeric adsorbent. CuII imprinted polyCuC15H11N2O2 microspheres have been synthesised by dispersion polymerisation technique through interaction of the template molecule CuII ion with the functional monomer. The specific surface area of CuII imprinted polyCuC15H11N2O2 microspheres was 374.26 m2g. The swelling rate was 80. The maximum adsorption capacity, the optimum pH and the adsorption equilibrium time were determined to be 153.03 mgg, in the 8-10 range and 30 min, respectively. The relative selectivity coefficients of the imprinted microspheres were found to be 13.09, 57.88, 44.719 and 35.006 for CuIINiII, CuIIPbII, CuIIZnII and CuIICoII, respectively. These results showed that the CuII-imprinted microspheres were more selective with respect to CuII ions. Reproducibility studies showed that CuII imprinted polyCuC15H11N2O2 microspheres can be used repeatedly without significant decrease in adsorption capacity.
