Abstract:The preparation of oxine-containing ion-exchange resins has been treated rigorously. The reactant ratios, nature of cure, degree of cross-linking and hydrophilicity have been evaluated in terms of metal capacity and kinetics of metal uptake. The preparation of a bead polymer with good physical properties is described; stability tests show that the gel polymers must never be allowed to dry, otherwise their advantageous properties are destroyed. Stability towards acids in re-cycling procedures is excellent in terms of metal capacity, but there is some loss in water regain which equates to a slower equilibration rate with constant use.
