Abstract
The synergistic solvent extraction of lanthanide ions with mixtures of 1‐phenyl‐3‐methyl‐4‐benzoyl‐pyrazol‐5‐one (HP) and the quaternary ammonium salt Aliquat 336 in chloride (QCl) or perchlorate (QClO4) forms in C6H6 was studied. The composition of the extracted species was determined as Q[LnP4] (Q+ is a quaternary ammonium salt cation). The values of the equilibrium constant were calculated. The extraction mechanism as well as the effect of the quaternary ammonium salt anion (Cl− or ClO4 −) on the extraction process are discussed. The separation factors of the lanthanide ions were determined on the basis of the experimental data. Some trends in the lanthanide separation were established.
