The impact of phase modification on the equilibrium and kinetics of lanthanide(iii) extraction from nitric acid media by TODGA.

ABSTRACT: Organic phase modification is a commonly implemented strategy to avoid third phase formation in f-element solvent extraction. For trivalent lanthanide extraction by neutral extractants in alkane diluents, such as N,N,N',N'-tetra(n-octyl)diglycolamide (TODGA) in n-dodecane, the addition of a phase modifier is necessary to operate at high organic acid and metal loadings. Phase modifiers such as tri(n-butyl)phosphate (TBP) and N,N-di(n-hexyl)octanamide (DHOA) have been proven to be effective at preventing organic phase splitting well beyond the critical concentrations that limit the TODGA/n-dodecane phase without any modifiers. While the extraction capacity and loading limits of lanthanide extraction from nitric acid
