Theory of Counter Current Extraction on Multi-Component Rare Earths(Ⅰ) Calculating Composition at Out Stage in Multi-component Cascade Extraction

对多组份稀土体系串级萃取分离的静态平衡出口级组成计算进行了研究,并给出了多组份稀土体系串级萃取分离的静态平衡出口级组成的计算公式,利用本文给出的计算公式可以比较精确,比较方便地计算出多组份稀土体系分离时出口级中各组份数的组成。

Calculation of the steadygoing composition at the out stage in multicomponent was studied, and the formulas were obtained. The formulas are convenient for using, and the calculated ratio of each element at out stage is relatively exact.
