摘要：

A low viscosity, hydrophobic eutectic solvent based on trioctylphosphine oxide (TOPO) has been developed and characterized, and its 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 high concentration of TOPO (ca. 80 wt %, 1.875 mol L-1 at chi(TOPO) = 0.50) and renders the use of an organic (hydrocarbon) diluent redundant.
