Laser-Induced Fluorescence Studies of Europium Extractant Complexes in Organic Phases.

摘要

Studies of Eu(sup 3+) extractant complexes in organic phases of interest in solvent extraction of lanthanides and actinides have been carried out using time- and wavelength-resolved laser-induced fluorescence (LIF). Even at low metal loading, the Eu(sup 3+) is shown to be present in the organic phase as a single metal ion- extractant complex in which complete dehydration of the metal ion has occurred when the aqueous phase was nitric acid and di(2- ethylhexyl)phosphoric acid or octyl(phenyl)-N,N,-diisobutylcarbamoylmethyl-phosphine oxide were used as extractants. 20 refs., 2 figs., 1 tab.
