摘要
The solvent extraction behavior of 13 lanthanides has been investigated using 1-phenyl-3-methyl-4-benzoyl-5-pyrazolone (HP) as an extractant in aqueous-benzene medium. The composition of the extracted species has been determined as LnP(3).HP. The values of the equilibrium constant as well as the separation factors between the adjacent elements have been evaluated.
