P507负载泡塑反相色层富集岩石中的稀土元素

Concentration of Rare Earth Elements in Rocks with HEH (EHP)Loaded Polyurethane Foam Col umn

摘要: 研究了Ｐ５０７负载泡塑萃取柱色谱分离富集稀土元素的条件，并与Ｐ５０７萃淋树脂柱进行了对比；拟定了Ｐ５０７负载泡塑反相色属富集岩石中稀土元素的方法。在ｐＨ２．５介质中ＲＥＥ上柱率９８％，用５０ｍｌ２．５ｍｏｌ／ＬＨＮＯ３作洗脱液，ＲＥＥ总回收率达９６．１％，干扰测定的Ｔｈ，Ｕ，Ｔｉ，Ｚｒ，Ｈｆ等均被除法。方法用于标样分析验证，结果与推荐值相符。

Abstract: he separation of interfering elements is effecled on a HEH(EHP)Loaded polyurethanefoam column.The method is more satisfactory than the use of a HEH(EHP)extraction resincolumn,as the behavior of some elements is different on the two columns, Concentrating
