我们研究了镝在0.10—0.22M/L 浓度范围内与二(2—乙基己基)磷酸的萃取平衡。镝的分配比随水相中盐酸初始浓度(0.0—1.0M/L)和镝初始浓度(0.10～0.22M/L)的增加而减小。经确定,在上述条件下,萃取机理属阳离子交换反应。
We studied the extraction balance of dysprosium with di (2-ethylhexyl) phosphoric acid in the concentration range of 0.10-0.22 M / L. The distribution ratio of dysprosium decreased with the initial concentration of hydrochloric acid (0.0-1.0 M / L) and the initial concentration of dysprosium (0.10-0.22 M / L) in the aqueous phase. It was confirmed that under the above conditions, the extraction mechanism is a cation exchange reaction.
