The results of a study of the sorption of uranium and the kinetics of isotopic exchange between uranium(IV) and uranium(VI) in a sulfuric acid-solution-titanium phosphate system have been presented. It has been shown that the sorption of uranium is limited by diffusion in the sorbent grains and that isotopic exchange is limited by the chemical reaction between uranium(IV) in the sorbent phase and uranium(VI) in the solution.
