Abstract

A closed cycle is demonstrated for the tandem dissolution and electroreduction of UO₃ to UO₂ with regeneration of the acidic ionic liquid. The dissolution is achieved by use of the acidic ionic liquid [DMAH][NTf₂] in [EMIM][NTf₂] serving as the diluent. A sequential dissolution, electroreduction, and regeneration cycle is presented.
