Abstract
Single stage separation factors have been determined for Li/sup 6/ and Li/sup 7/ between aqueous lithium ions and lithium ions on sulfonated polystyrene- divinylbenzene copolymers of various degrees of crosslinking. A band elution technique on an ion-exchange column was used. The single stage separation factor, alpha , (Li/sup 6//Li/sup 7/) resin/(Li/sup 6// Li/sup 7/)aqueous, was determined according to the method of Glueckauf from the elution curve anid isotopic assays. Variations in alpha (1.0006 to 1.0038) with the degree of crosslinking can be explained by a simple concept of partial dehydration of lithium ions in the resin phase. Assuming a model for the lithium ion species in the two phases, the magnitude of alpha can be estimated quantum mechanically. (auth)
