Extraction of Ln(III), Sc(III), Ga(III), and Re(VII) ions by solutions of phosphorylated monopodands having [ortho-(diphenylphosphinylmethyl)-para-methyl]phenyl terminal groups, 2-Ph₂P(O)CH₂(4-Me)C₆H₃(OCH₂CH₂)_nOC₆H₃(Me-4)CH₂P(O)Ph₂-2 (n = 1–5), in organic solvents has been studied. The stoichiometries of extractable complexes were determined. The effect of the aqueous phase, organic solvent, and phosphorylated podand structure on the efficacy of metal-ion recovery into organic phase has been considered.
