The Active Transport of Ions of Rare-Earth Elements, Alkali Metals, Al(III), and Mg(II) with New Lipophilic N,N-Bis[(Dihexylphosphoryl)Methyl]Octylamine

Abstract

The Active Transport of Ions of Rare-Earth Elements, Alkali Metals, Al(III) and Mg(II) with N,N- Bis[(dihexylphosphoryl)methyl]octylamine was studied. It is found that with the selected reagent the flow of ions S?(III) and Nd(III) is several times higher than the flow of ions Al(III) and Mg(II). Also, the mixtures of bis(aminophosphoryl) reagent and mono-/dithiophosphoric acids show evidence for synergistic effects with high selectivity when used for the extraction of Li(I).
