ADSORPTION SELECTIVITY FOR Cu~(2+),Ni~(2+),Co~(2+)IONS USING CROSSLINKING CHITOSAN RESINS IMPRINTED BY METAL IONS

HUANG Wenqiang; HAN Lijun;LI Chenxi;HE Binglin(The State Key Laboratory of Functional Polymer Materials for Adsorption and Separation,Institute of Polymer Chemistry Nankai University University,Tianjin 300071, China)  
Metal ion-imprintedly crosslinked chitosan resin 1 and resin 2 were prepared by theuse of Cu~(2+) and Ni~(2+) as template ions and glutaraldehyde as crosslinking agent, respectively.Through investigation on the adsorption capacities and binding constants for Cu~(2+), Ni~(2+)andCo~(2+) ions on chitosan resins, resin 1 and resin 2 exhibit the adsorption selectivity for themixture solution of 1:1 Cu2+ and Ni2+ ions. The adsorption selectivity of metal ion-imprintedresins for their template ions is much higher than that of uncrosslinked chitosan resin.
