Extraction of lanthanides from a solution of disodium ethylenediaminetetraacetate with methyl-tri-n-octylammonium chloride in benzene


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 andLnY at pH lower than 7.
