摘要

The polymer resin 8-HQ5-SAMF-II was synthesized by the condensation of 8-Hydroxyquinoline5-sulphonic acid (8-HQ5-SA) and melamine (M) with Formaldehyde (F) in the presence of acid catalyst at 130°C proved to be a selective chelating ion exchange polymer for certain metals. The eco-friendly applications of this polymer resin was studied with respect to its chelating ion-exchange properties The chelating ion-exchange properties of this synthesized polymer was studied for different metal ions such at Fe3+, Cu2+, Ni2+, Co2+, Zn2+, Cd2+ and Pb2+. A batch equilibrium method was employed in the study of the selectivity of metal ion uptake involving the measurements of the distribution of a given metal ion between the polymer sample and a solution containing the metal ion. The study was carried out over a wide pH range, shaking time and in media of various ionic strengths. The polymer showed a higher selectivity for Fe3+, Cu2+and Ni2+ ions than for Co2+, Zn2+, Cd2+ and Pb2+ ions.
