Abstract
Extraction of rare earth elements with bis(diphenylphosphorylmethyl) ethers of oligoethylene glycols Ph2P(O)CH2O(CH2CH2O)nCH2P(O)Ph2 (Ln, n = 0–5) in 1,1,7-trihydrododecafluoroheptanol–water system with variable HNO3 concentration from 0.5 to 6 mol/L has been studied Complexes of Nd, Eu, Lu, and Er nitrates with L0 and L2 have been obtained. Crystal structures of [Ln2L30(NO3)6] · xH2O (Ln = Nd, x = 1.99; Ln = Eu, x = 1; Ln = Er, x = 6.5; Ln = Lu, x = 6) and [LnL2(NO3)3(H2O)] (Ln = Nd, Er) have been studied by X-ray diffraction, IR spectroscopy, and thermogravimetry. Correlation between X-ray diffraction and extraction data has been revealed.
