Abstract

Chelating ion-exchange resin was synthesized by the condensation of 8-hydroxyquinoline with pyrogallol using formaldehyde as a cross-linking agent at 120ºC in DMF in the presence of hydrocloric acid catalyst. The resin was characterized by elemental analysis and FTIR. The morphology of the synthesis resin was examined by optical photograph and scanning electron microscopy (SEM).The physicochemical properties of the resin were studied. The cation exchange capacity was measured and the effect of pH and metal ion concentration on the ability of the ion exchange were studied. The ratio of cation exchange reaction and the distribution coefficient in tartaric acid medium at different pH were also studied using the method of batch equilibration.
