修饰聚合物盐水液-固萃取体系分离钪(Ⅲ)和镨(Ⅲ)的研究

究了Sc和Pr在聚乙二醇 亚氨基二乙酸 (简称PEG IDA)混合Tween 80 盐 水液 固萃取体系中的分配行为 ,讨论了修饰物用量、萃取酸度、吐温用量及分相盐种类和浓度对其萃取率的影响 ,筛选出最佳萃取分离条件 ,控制萃取酸度 ,实现了Sc和Pr的分离。并用pH电位法在 3 0℃的 0 .1mol·L- 1 KNO3溶液中测定了PEG IDA的离解常数以及PEG IDA与Sc和Pr形成的配合物的稳定常数 ,研究了稳定常数与稀土在PEG IDA修饰聚合物 盐 水液 固亲和萃取体系中分配行为的关系 ,并据此对该体系富集分离稀土的机制进行了初步探讨。结果表明 :Sc和Pr是通过与PEG IDA形成配合物而被萃入固相的。
