Outline of Final Research Achievements

In this study, metal recognition gels were prepared by introducing metal ligands into saccharide and organizing them. The molecular imprinting technique was used for preparing the gels. When In (II) imprinted gel was prepared using the ion complex of chitosan and alginic acid introduced histidine or thiourea as a ligand, the gel could not show sufficient In (II) selectivity. On the other hand, the imprinted gels prepared using the high density crosslinked saccharide showed the In (II) selective adsorption.
