A procedure of micellar extraction of the lanthanide ions (La, Gd, and Lu) from nitric acid media based on the use of novel phosphine oxide derivatives is developed. In the micellar extraction, complexes of the lanthanide ions with the extractant in the ratio of 1: 2 (metal: extractant) form. The dependence of the selectivity of extraction on the length of hydrophobic radicals attached to the P=O group was shown. The conditions of the selective micellar extraction in the series La > Gd > Lu with the use of an extractant containing octyl substituents at the P=O group were found.
