The Impact of Template Types on Polyeugenol to the Adsorption Selectivity of Ionic Imprinted Polymer (IIP) Fe Metal Ion

摘要

The synthesis of IIP was carried out by variation of Fe(III) ion templates from Fe(NO3)3, Kj[Fe(CN)6] and NH4Fe(SO4)2 compounds which then tested IIP selectivity to the Fe metal ions through adsorption process. Ionic Imprinted Polymer (IIP) is a method of printing metal ions bound in a polymer, subsequently released from the polymer matrix to produce a suitable imprint for the target ion. The purposes of this study were to produce IIP from Fe(NO3)3, K3[Fe(CN)6] and NH4Fe(SO4)2 templates, to know the effect of templates on adsorption selectivity of IIP involving imprint cavity, and to know the impact of metal competitor on the selectivity adsorption of IIP to the Fe metals. The results obtained showed that IIP synthesized by variations of Fe(NO_3)_3, K3[Fe(CN)_6] and NH4Fe(SO_4)_2 templates were successfully synthesized. The adsorption selectivity of Fe (III) metal ion in the Fe(NO_3)_3 template was greater than that of in the K3[Fe(CN)6] and NH4Fe(SO_4)_2 templates. The adsorption selectivity of Fe was greater on Fe-Cr compared to on Fe-Cd and Fe-Pb.
