Swami, K. Rama published the artcileUnraveling 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, SDS of cas: 111-87-5, the main research area is neodymium extraction nitric acid TEHDGA dodecane alc phase modifier.
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 alcs. 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 alcs. investigated were n-octanol, n-decanol, and isodecanol. To understand the role of alcs. in controlling the third phase formation, the extraction behavior of the trivalent metal ion, Nd(III), from nitric acid medium was studied in a solution of 0.2 M TEHDGA + 1 M alc. in n-DD. The equilibrium concentration of Nd(III) and nitric acid present in organic and aqueous phases were determined The organic phase obtained after extraction was subjected to dynamic light scattering studies to unravel the role of alc. phase modifiers in organic phase. The aggregate size and their distribution in organic phase was determined as a function of various parameters such as concentrations of nitric acid, Nd(NO3)3 and the nature of alc. In view of this, the aggregate size was controlled much below the limiting aggregate size required for third phase formation by these alc. phase modifiers. Even though all the alcs. investigated in the present study could bring down the aggregate size much below the limiting value, n-decanol was found to be superior to other alcs.
