Theoretical Derivation of Separable Yield in Dynamic Extraction of Recoil Products from an Ion-Exchanger Loaded with Target Ion during Neutron-Irradiation

抄録

As a contribution to the dynamic irradiation-elution method using ion-exchanger, in which, duringthe progress of irradiation, the product resulting from irradiation is immediately separated upon recoilfrom the complex-ion target adsorbed on an ion-exchanger, the concentration of the separable recoilingspecies remaining in the bead and the film of the ion-exchanger in stationary condition was derivedtheoretically as a function of bead radius, with parameters to account for various others factors suchas initial yield, film thickness, recombination rate constant of the recoiling species, and their diffusioncoefficients. The equation derived for the separable yield was applied successfully to the analysisof experimental results obtained on trioxalatochromium ion adsorbed on an ion-exchange resin.
