Abstract
The solvent extraction of La, Nd, Eu, Ho and Lu with thenoyltrifluoroacetone (HTTA) and the quaternary ammonium salt Aliquat 336 in chloride (QCl) or perchlorate (QClO4) form in CHCl3, C6H6, CCl4 and C6H12 has been studied. On the basis of the slope analysis data, the composition of the extracted species was determined as Q+[Ln(TTA)4]− (Q+ is the quaternary ammonium salt cation). The values of the equilibrium constant and the separation factors were calculated. The effect of the diluents on the metal extraction and separation has been discussed.
