Ionic Liquids: How Far Do they Extend the Potential of Solvent Extraction of f-Elements?

摘要: Applicability of room temperature liquids (RTILs) as diluents in the solvent extraction f-elements is reviewed. Characteristics selected RTILs, important for such an application, are gathered. Properties tabulated melting and freezing points, density, mutual solubility with water, viscosity, surface tension, specific conductivity, radiation stability. environmental compatibility, toxicity, chemical thermal stability, biodegradability, degradability imply that RTILs not harmless to environment or work safety. The efficiency mechanism systems involving described, discussed, compared molecular diluents. Particularly assessed nitric acid by alone TBP, U(VI), Ce(IV), Pu(IV), Am(III), lanthanides(III) alone, actinides(III,IV), solvating O-donors, Eu(III) a ...
