Jp. Shukla et al., INFLUENCE OF GAMMA-IRRADIATION ON EXTRACTION AND CATION-TRANSPORT OF URANIUM(VI) AND PLUTONIUM(IV) BY DICYCLOHEXANO-18-CROWN-6, Journal of Nuclear Science and Technology, 31(10), 1994, pp. 1066-1072
Changes of the extraction behaviour and cation-transport of U(VI) and
Pu(IV) nitrates with gamma-irradiated DC18C6 in toluene have been inve
stigated. The effect of radiation damage to DC18C6 for extraction and
permeation at excessively higher doses (70 Mrads) has been studied sys
tematically. No deterioration in its performance is noted at lower dos
es. Hydrolytic stability of the macrocycle/diluent system in the prese
nce of nitric acid and radiolytic stability of immobilized liquid memb
rane using 'Enka' Accurel flat sheet polypropylene membrane films as s
olid support are also examined.
