Abstract: The mechanism of the synergistic extraction of 15 trivalent rare earth ions with HPMBP and TPhPO was investigated by the two-phase titration method. The compositions and the stability constants of synergistic complexes were determined at temperature of 15℃, 25℃, 35℃.

Key words: RE,PMBP,TPhPO, Synergistic extraction
