Abstract
The practical sorption capacity, rate of establishment of the sorption equilibrium, pH-dependence of the distribution coefficient of Cu2+ ions, sorption isotherm, and stability of the ion exchanger were determined and mutually compared for two different ways of fixation of 8-hydroxyquinoline to glycidyl methacrylate gel (G-gel). The effect of the ion exchanger particle size on some of its properties was also investigated. In the ion exchanger obtained by direct fixation of copper(II) 5-(4-hydroxyphenylazo)-8-quinolinate, the modified reagent retains a steric arrangement suitable for chelation.
