| Abstract: | Tercopolymer (8-HQBF) prepared by condensation of 8-hydroxyquinoline (8-HQ) and biuret (B) with formaldehyde (F) in the presence of 2M HCl as catalyst was proved to be a selective chelating ion-exchange tercopolymer for certain metals. Chelating ion-exchange properties of this tercopolymers are studied for Fe3+, Cu2+, Ni2+, Co2+, Zn2+, Cd2+ and Pb2+ ions. A batch equilibrium method has been 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 has been carried out over a wide pH range and in media of various ionic strengths. The polymer shows a higher selectivity for Fe3+, Cu2+ and Ni2+ ions than for Co2+, Zn2+, Cd2+ and Pb2+ ions. |
