摘要：

The synergistic solvent extraction of Pr,Gd and Yb with mixtures of 1-phenyl-3-methyl-4-benzoyl-pyrazol-5-one(HP) and a crown ether benzo-15-crown-5(B15C5 or S) in CCl4,C6H6 and CHCl3 has been studied.The composition of the extracted species has been determined as LnP3.nS where Ln=Pr,Gd and Yb and n=1 or 2.Mixed complexes LnP3.S have been found when C6H6 and CHCl3 were used as diluents and both LnP3.S and LnP3.2S - when CCl4 was used.The influence of the diluents on the extraction process has been discussed.
