| Abstract: | Cerium chloride rare earth solution was extraced by binary synergistic extraction system composed of P204 and P350.The effects of oscillation time, phase ratio and rare earth ion concentration on extraction rate were studied.The results show that when the P204 and P350 system oscillation time was 9 min, the ratio was 1∶1,rare earth ion concentration was 0.1 mol/L,the synergistic extraction system had the best effect of extraction, the extraction rate was 71%.The characteristic peak of extraction phase in infrared characterization can qualitatively indicate the occurrence of extraction reaction. |
