Abstract

A low viscosity, hydrophobic eutectic solvent based on trioctylphosphine oxide (TOPO) has been developed, characterized, and it’s use as an extractant demonstrated for liquid-liquid separation of uranyl nitrate from aqueous acid. This strategy of liquefying the active extracting agent as a eutectic liquid, produced liquids that contain an intrinsically concentration of TOPO (ca. 80 wt%, 1.875 moles L–1 at χTOPO = 0.50) and render the use of an organic (hydrocarbon) diluent redundant.
