Data Compilation. The compilation of literature meta-data is focused upon representative nonionic diglycolamide, phosphate and monoamide extractants employed in the separations of actinides and lanthanides: N,N,N',N'-tetraoctyl diglycolamide (TODGA), tetra(2-ethylhexyl) diglycolamide (TEHDGA), N, N'-Dimethyl, N, N'-dioctyl hexylethoxy malonamide (DMDOHEMA), and tributyl phosphate (TBP) as well as the metal ions Am and Eu. From 35 sources, we first identified the temperature dependent initial and equilibrium concentrations for the extractant, solvent, acid, and metal content, as well as the metal distribution coefficients, and (when available) third phase formation conditions. A representative plot of the span of experimental conditions, listed as the initial extractant vs. acid concentration, is shown in Figure . All data for this work has been deposited in the recently published SAFE public repository for solvent extraction data at .
