Separation of thulium, ytterbium and lutetium from uranium
Description
The behaviour at different temperatures, shaking times and hydrochloric acid concentrations on the solvent extraction system UO22+ - (Tm3+, Yb3+, Lu3+) - H2O - HCl - TBP was studied. Quantitative determinations of the elements were performed by visible spectrophotometry and X-ray fluorescence. The uranyl ion was efficiently extracted by TBP from an aqueous hydrochloric acid solution (4-7M) shaken during 10 minutes at room temperature. On these conditions the separation factors for uranium from thulium and ytterbium were found to be 3000 and from lutetium 140. (author)
