Solvent extraction of actinide ions by -dioctyldiglycolamic acid

Sugo, Yumi; Sasaki, Yuji ; Kimura, Takaumi ; Sekine, Tsutomu*

Solvent extraction of Am(III), Pu(IV), Np(V), and U(VI) from aqueous HNO $_{3}$ solution was performed using -Dioctyldiglycolamic acid (DODGAA) dissolved in -dodecane. It was found that DODGAA had high extractabilities for Am(III) and Pu(IV) from dilute HNO $_{3}$ into -dodecane. The distribution ratios of these actinide ions decrease with increasing HNO $_{3}$ concentration, indicating that DODGAA acts as an acidic type ligand.
