摘要：

The influence of the interaction between the extractants 1-phenyl-3-methyl-4-benzoyl-5-pyrazolone (HP) and Aliquat 336 in chloride (QCl) and perchlorate (QClO(4)) form in C6H6 on the synergistic extraction of Pr has been studied. It was found that at the experimental conditions of the present study the concentration of the ion-pair QP obtained as a result of the interaction of the extractants is low and that the synergistic agent is the quaternary ammonium salt. The values of the equilibrium constant K-exc for the interaction between the extractants as well as of K-P,K-Q and beta (P,Q) for the synergistic extraction of Pr have been calculated. The influence of the ammonium salt anion on the extraction process has been discussed.
