The mixture of Triton X100 and novel dialkyl(diaryl)2-hydroxyphenyl-alkenylphosphine oxides and dialkyl(diaryl)-(2-methyl-4-oxopent-2-yl)phosphine oxides derivatives has been optimized for the extraction of lanthanide ions (La(III), Gd(III) and Lu(III)) from rather acidic media (pH=1) with the use of temperature induced phase separation in mild conditions. Both the extraction efficiency and selectivity have been analyzed for the wide range of phosphine oxide derivatives with hydroxyl, methoxyl or carbonyl group of the various structure and hydrophobicity. The obtained results indicate that both the efficiency and selectivity of micellar extraction are greatly affected by the electron donor capacity of P=O group, which is affected by the length of the hydrophobic substituents neighboring to P=O group. The latter are varied from n-C4H9 to n-C8H17. No effect of the aryl substituents has been found. Though all studied chelating agents exhibit the enhanced extractability towards La(III) ions, the extraction selectivity is the worse for the most efficient chelating agent and vise versa. It has been found that the high hydrophilicity of phosphine oxides does not restrict their use as chelating agents, though they provide less efficient extraction than their more hydrophobic counterparts. The absence of the so-called “third phase” and high concentration (ten-fold and more) of the extracted lanthanides within the surfactant rich phase are the advantages of the developed extraction procedure as compared to the well known liquid-liquid extraction technique.
