Abstract

Changes of the extraction behaviour and cation-transport of U(VI) and Pu(IV) nitrates with γ-irradiated DC18C6 in toluene have been investigated. The effect of radiation damage to DC18C6 for extraction and permeation at excessively higher doses (70 Mrads) has been studied systematically. No deterioration in its performance is noted at lower doses. Hydrolytic stability of the macrocycle/diluent system in the presence of nitric acid and radiolytic stability of immobilized liquid membrane using 'Enka' Accurel flat sheet polypropylene membrane films as solid support are also examined.
