Abstract
The separation efficiency of metal ions by using the poly-NTOE(1, 12-diaza-3, 4:9, 10-dibenzo-5, 8-dioxacyclopentadeca-1, 12-ylene-2, 7-dihydroxyoctamethylene) has been determined by column chromatography in aqueous solution. Binding constants and separation factors for several poly-NTOE interactions were measured in aqueous solution. The order of these binding constants and separation factors with metal ions were Co(II)<Ni(II)<Cu(II)>Zn(II) for the transition metal ions and Cd(II)<Pb(II)<Hg(II) for the post transition metal ions. These results were explained in terms of the Irving-Williams series and entropy of desolvation. This experimental results showed good efficiency for separation of Hg(II) from mixtures of transition metal ions and post transition metal ions in aqueous solution.
