Abstract
The ion-exchange and sorption characteristics of new polymeric composite resins, prepared by gamma radiation were experimentally studied. The composite resins show high uptake for Co(II) and Eu(III) ions in aqueous solutions in a wide range of pH. The selectivity of the resins for Co(II) or Eu(III) species in presence of some competing ions and complexing agents (as Na+, Fe3+. EDTANa(2), etc.) was compared. Various factors that could affect the sorption behavior of metal ions (Co(II) and Eu(III)) on the prepared polymeric composite resins were studied such as ionic strength, contact time, volume mass ratio.
