摘要：

The synergistic solvent extraction of Pr, Gd and Yb with mixtures of 1-phenyl-3-methyl-4-benzoyl-5-pyrazolone (HP) and tridecylammonium chloride or perchlorate (TDAHCl, TDAHC10(4)) in C6H6 was studied. The composition of the extracted species was determined as TDAH[LnP(4)]. The values of the equilibrium constant as well as the values of the synergistic coefficient and separation factor were calculated. The influence of the synergistic agent (TDAHCl or TDAHClO(4)) on the extraction process is discussed. (C) 1998 Elsevier Science B.V.
