Fundamental studies on the ion exchange separation of isotopes, (vi)

Abstract

Ion exchange separation factors for the quaternary valence isotopes forming stepwise complexes in external solutions have been theoretically evaluated. Two forms of the limits for the separation factors were found both for the anion exchanger and the cation exchanger systems. For the anion exchanger, [Formula omitted] On the anion exchanger system, in case only AX5 being adsorbed on and the very large excess of A existing in the external solution, the effect by five times as large as the ratio of the stability constants of one step complex formation is expected on the separation factor. On the cation exchanger, the highest effect is expected when only A is adsorbed on and the very large excess of AX6 exists in the external solution. The value for the effect is approximately six times as large as the ratio of the stability constants of one step complex formation. © 1963, Atomic Energy Society of Japan. All rights reserved.
