The adsorption of Pd(II) and Cu(II) on macroporous hydrophilic glycolmethacrylate gels with side chains containing 8-hydroxyquinoline (Spheron Oxine 1000), thiol (Spheron Thiol 1000) and salicyl groups (Spheron Salicyl 1000) has been investigated. Palladium is strongly adsorbed by Spheron Oxine and Spheron Thiol resins from a hydrochloric medium. The influence of pH and ionic strength has been determined. The elution of Pd(II) was carried out by using acidified thiourea or potassium thiocyanate solutions. Desorption was most effective for Spheron Oxine resin. The kinetics of metal adsorption by Spheron Oxine 1000 was also studied. The experimental data were analyzed numerically by considering both the forward and the reverse reaction, and corresponding constants are calculated for different initial metal and resin concentrations. Separation of aqueous mixtures of Pd(II) and Cu(II) by using Spheron Oxine is discussed. © 1994.
