摘要
研究了 PMBP 以环己烷为稀释剂萃取钪和镥的机理,补充了有关 PMBP 萃取钪的数据.本体系中钪和镥的 pH_(1/2)分别为2.85和2.86.对 PMBP 萃取色谱法分离钪和镧系元素及钇的条件进行了选择.该方法可应用于离子型稀土矿中微量钪的分离和分析.
Mechanism of the extraction of scandium and lutetium with PMBP/ was studied in this paper,and the extraction data about scandium with PMBP were supplied.In this sys- tem,the pH_1/2 of scandium and lutetium were 0. 85 and 2.86,respectively.The separation conditions of PMBP-extraction chromatography were also chosen.This method can be ap- plied to the separation and analysis of microamount of scandium in the ion-type rare earth ore.
