Extraction of Technetium from Uranium
Invention SummaryA spent fuel reprocessing method contacts an aqueous solution containing technetium(V) and uranyl with an acidic solution comprising hydroxylamine hydrochloride or acetohydroxamic acid (AHA) to reduce technetium(V) to technetium(II), and then extracts the uranyl with an organic phase, leaving technetium(II) in aqueous solution.Market...

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...
