Title: A study on in-situ electrolytic stripping of uranyl ion by using a closely packed glassy carbon fiber column electrode system

Abstract

Uranium(VI) in a tributyl phosphate organic phase was stripped into an aqueous phase by reduction of uranium(VI) to uranium(IV) in a closely packed GC fiber column electrode system. A model for in-situ uranium(VI) electrolytic stripping was suggested for the system. Uranium(VI) electroreduction occurred both in the organic phase and in the aqueous phase of the mixed phases. The uranium stripping yield increased and then became constant with the organic flow rate in the electrolytic system due to an increase of diffusion resistance of uranium ions in the organic phase into the aqueous phase. The aqueous flow rate, on the other hand, did not significantly affect the total uranium(VI) reduction current in the system. Electrolytic stripping was confirmed to be more effective than ordinary stripping without electrolysis.
