| Abstract: | The extraction of Pr, Eu and Yb from a solution of NH4SCN at pH<2 with a solution of Aliquat-336—SCN in benzene has been investigated. The formation of the following kinds of extractable complexes in dependence of NH4SCN and H2SO4 was established: [Ln(SCN)4]–1, [Ln(SCN)5]–2, [Ln(SCN)6]–3.
