摘要
用P_(204)、P_(507)萃取轻稀土中镨元素的分离萃取性能进行研究,在不同的萃取相比、不同的原液pH值、不同萃取剂浓度、不同的萃取震荡时间、不同助萃剂体积分数等条件下设计了实验方案,通过反复的实验后对萃取条件进行优化,使得P_(204)、P_(507)对轻稀土中镨元素的分离萃取中发挥更好性能。
In this paper, the extraction properties of the praseodymium in light rare earth extracted with P204 and Ps07 were studiedand narrated. Experiments are carried out under the conditions of different extraction factors, ph value, extractant concentration,duration of oscillation and extractant volume fraction. With repeated trials, reasonable improvements are made to the extractionconditions, which have enabled the extraction properties of the praseodymium in light rare earth extracted with P204 and P507 toperform better.
