摘 要：<正> The stripping and regeneration of the loaded organic phase of phosphorous mixer extractant （PPD） were studied. The mixed solutions （3 niol/L HC1 +2 mol/L ZnCl2） were used as the stripping agent and more than 99% of indium can be stripped after three-stage stripping when the volume ratio of organic phase to stripping agent is 1:1. The organic phase can be recycled to use after regeneration with HC1. The parallel contrast experiments with D2EHPA （di-2-ethyl hexyl phosphoric acid） were carried out under the same conditions. The results show that the mixer extractant has good reusability and the stripping and regeneration of PPD are superior to those of DJ3HPA.
