Dehydration from tris[[beta]-diketonato]lanthanoids(III) on the 1,10-phenanthroline adduct formation across lanthanoid series.
The synergistic extraction of trivalent actinoids and lanthanoids is of great interest because of the high extraction efficiency of these metal ions in the presence of a chelating agent and a neutral donor [1-7].
The distribution coefficients of the lanthanoids were determined in three series of experiments:
P,S] versus the atomic number Z of the representative lanthanoids is given in Fig.
It is evident that all lanthanoids are extracted synergistically (S.
The separation of the lanthanoids using HTTA-PAR and HP-PAR mixtures can be assessed by the separation factors calculated as a ratio of the distribution coefficients of two adjacent lanthanoids (the heavier and the lighter one).
