| 摘 要： | 用普通分馏萃取工艺分离物质一次只能分离两个组份,若连续分离多种物质,则需很长工艺流程.文献1]报导了用N_(26?)萃取分离La-Pr-Nd的三出口串级实验结果.本文报导用氨化HEH(EHP)同时萃取分离Gd-Tb-Dy的串级试验结果.

| Abstract: | A simultaneous separation experiment for Gd-Tb-Dy with ammoniated HEH(EHP) wascarried out. The scheme of separation is described and the products separated from threeexists had the following purities: La-Gd 99.99%, Tb 68.9%, Dy-Lu 99.8%. |
