| 摘 要： | 研究了在P_(507)-HCl-(NH_4)_2SO_4体系中用萃取色层法定量分离钕、钐、铕、钆、铽和镝的条件,实验表明当用0.42mol/L HCl-0.5mol/L(NH_4)_2SO_4作淋洗剂时,上述元素都能定量分离。方法能用于钐、铕、钆富集物中钐、铕、钆和铽的测定。

| Abstract: | The conditions for quantitative separation of Nd-Sm-Eu-Gd-Tb--Dy have been studied by using extraction-chromatographic technique in P_(507)-HCl--(NH_4)_2SO_4 system. The experiments show that the elements can be separated quantitatively by Using 0.42mol/L HCl-0.5mol/L (NH_4)_2SO_4 as eluant. This method can be applied to determine Sm, Eu, Gd and Tb in the Sm-Eu-Gd concentrate. |
