| 摘 要： | 研究了以ＥＤＴＡ为排代剂，用高压离子交换螯合排代法分离重稀土元素时，不同的阻滞离子对分离效果的影响．阻滞离子－树脂的亲合力和阻滞离子－排代剂络合物的稳定性是阻滞离子影响稀土元素分离效果的２个因素．在稀土分离中，选择阻滞离子时，综合考虑上述２个因素，是实现有效分离的关键之一．

| Abstract: | The paper researched that the effect separation heavier rare earths is influenced by separate retaining ions with high pressure ion exchange displacement process. Affinity of retaining resin and stability of retaining ion-displacer are two factors affected efficiency of rare earths separation,which should be important in selection. |
