AbstractAbstract
[en] The extraction of Pr, Eu and Yb from a solution of Komplexon III (a disodium salt of ethylenediamine-tetraacetic acid) at constant ionic strength with a solution of Aliquat-336 (tri-n-octyl-methylammonium chloride) in benzene has been investigated. The dependence of the distribution coefficient on the pH of the aqueous phase was studied. The formation of the following kinds of extractable complexes was established: for Eu and Yb: LnY(OH)2-, for Pr: LnY(OH)23- at pH=ca.9 and LnY- at pH lower than 7. (author)

AbstractAbstract
[en] 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

AbstractAbstract
[en] The extraction of some lanthanides from the aqueous phase of ionic strength μ=0.05 by mixtures of thenoyltrifluoroacetone and pyridine bases such as 3- and 4-methylpyridine, 2,6-dimethyl-pyridine, 2,4,6-trimethyl-pyridine and piperidine in CCl4 has been investigated. The synergic effect observed is explained in terms of the formation of mixed tetra-β-diketonate complexes of the type LnX4CH. (author)

AbstractAbstract
[en] The synergic extraction of praseodymium by mixtures of tributylphosphate and Aliquat-336 (nitrate, thiocyanate and perchlorate forms) has been investigated. The composition of the extracted complexes has been determined. The influence of the employed solvents and the different forms of the quaternary ammonium salt are discussed. (author)
