Unraveling the role of phase modifiers in the extraction of Nd(III) from nitric acid medium in tetra-bis(2-ethylhexyl)diglycolamide in n-dodecane containing long chain aliphatic alcohols

Tetra-bis(2-ethylhexyl)diglycolamide (TEHDGA) alone in n-dodecane (n-DD) is unsuitable for the solvent extraction of trivalent actinides from high-level liquid waste due to the occurrence of third phase formation during the course of solvent extraction. Significant concentration of long chain aliphatic alcohols ranging from 5% to 15% (V/V) have been added to the solvent phase, TEHDGA/n-DD, to control the undesirable third phase formation. The...
