High concentration of Cs is present in high-level radioactive waste. It well-known that an alkali element and difficult to extract completely into organic phase. Crown ether compounds are widely available for extractants; DtBuDB18C6 (di-t-butyl-dibenzo-18crown6), was used this study. Organic solvents the industrial applications, such as n-dodecane 1-octanol, have low solubility concerning compo...

This work studies the solvent extraction of lithium ions from alkaline aqueous solutions by chelating agent 3-benzoyl-1,1,1-trifluoroacetone (HBTA). To develop a more eco-friendly system for than currently used, various hydrophobic room-temperature ionic liquids were investigated as diluents. The influence several experimental parameters on was examined, including phase pH, nature counter-ion, ...
