Methods for Controlled Recovery of Useful Materials from Nuclear Fuels
Invention SummaryThe methods would allow nuclear materials—lanthanides and actinides—to be dissolved directly into ionic liquid for electrochemical recovery, reducing the number of steps and the negative influence of water in the process. The same ionic liquid serves as an electrochemical bath for the plating of actinides and lanthanides...
