放射性示踪法研究Rn和Pt,Pd,Ir的萃取分离—Rh的提纯

    STUDY ON THE EXTRACTION SEPARATION OF Rh FROM Pt,Pd,Ir BY RADIOTRACER METHOD——PURIFICATON OF Rh

    • 摘要: 本文研究了在不同条件下,TOA-煤油溶液对Pt,Pd,Ir的萃取。在低酸度盐酸介质条件下,用TOA-煤油溶液作为萃取剂可以达到Rh与Pt,Pd,Ir的定量分离。萃取的平衡时间短,分相快。萃取剂可再生使用。用本方法分离经精制获得的金属Rh产品纯度可达>99%。

       

      Abstract: In this work the extraction of Pt, Pd, Ir by TOA-kerosin under different conditions is studied. In HC1 medium of low acidity Rh is quantitatively separated from Pt, Pd, Ir by TOA-kerosin as extractant. The equilibrium time of extraction is short and the split phase rate is fast. The extractant can be used by cyclic regeneration. By this method, the purity of metal product Rh is about>99%.
