利用选择性特效树脂富集分离岩石样品中的锶钐和钕

Separation of Sr, Sm and Nd in Mineral and Rock Samples Using Selective Specific Resins

摘要: 使用目前国际上几种常用的特效树脂:锶树脂(SR)、稀土树脂(RE)和镧系树脂(LN)对岩石样品中Sr、Sm和Nd的分离富集效果进行了试验,结果表明,按厂家提供的流程,SR树脂可回收98%左右的Sr,而且残余的Rb不到2%;RE树脂回收的Sm和Nd只有70%左右;而联合利用RE和LN树脂,并配合SR树脂的使用,可以将Sm和Nd的回收率提高到90%左右;LN树脂可以很好地分离Sm和Nd,并且回收的Nd可占总样量的85%左右。
