Abstract
The characterization and possibility of the practical use of different polymeric materials for the purpose of radioactive isotope separation from their wastes were studied. The influence of chemical treatment on the chelation or adsorption capacity at 25 °C was investigated. The equilibrium swelling of these polymers in distilled water at room temperature and the effect of solvent composition on the graft yield were also explored. In this study, the mechanical, chemical resistance and other properties for the grafted, untreated, and treated membranes were investigated. The performance of the membranes was studied as a function of time and degree of grafting. The effects of chemical treatment on the initial activity and separation of Tc-99m have also been examined. The base polymer and degree of grafting have great influence on the Tc uptake. © 2001 John Wiley & Sons, Inc. J Appl Polym Sci 81: 1207–1215, 2001
