Separating Lanthanides and Actinides from Nitric Acid Solutions by Using N,N-di(2-ethylhexyl)-diglycolamic Acid (HDEHDGA)

Abstract

The extraction of Eu(III), U(VI), and Pu(IV) from 0.1 – 3 M HNO3 solutions by using N, N-di(2-ethyl-hexyl)-diglycolamic acid (HDEHDGA) is presented. In contrast with common organic acidic extractants, such as long-chain carboxylic acids, organophorspors acids, and derivatives of beta-diketones, which lose extractability, HDEHDGA exhibits strong capability to extract lanthanide and actinide ions from high HNO3 solutions.
