Studies on the extraction of plutonium(IV) from aqueous nitric acid - oxalic acid by aliquate-336

Journal Article · · Solvent Extr. Ion Exch.; (United States)
The extraction of Pu(IV) by Aliquate-336 from aqueous nitric acid containing oxalic acid was studied with a view to exploring the feasibility of recovery of Pu(IV) from Pu(IV) oxalate precipitation effluents. Distribution ratio data were obtained as a function of concentration of nitric acid, oxalic acid and Aliquate-336. The data obtained revealed that Pu(IV) can be extracted almost quantitatively by 20% Aliquate-336 in xylene from aqueous medium containing oxalic acid up to 0.25 M provided the nitric acid concentration is greater than or equal to 4 M. These data suggest that Pu(IV) can be recovered directly from nitric acid - oxalic acid waste generated in Pu-oxalate precipitation by Aliquate-336 extraction. 6 tables.
