| 摘 要： | 以多元稀土串级萃取体系的状态方程为基础，引入等效分离系数，将多元串级萃取体系描述为对分离系数进行修正后的等效双组分分离体系；提出了等效分离系数的计算方法，并对多元串级革取的分高工艺进行设计计算．计算机仿真结果表明，等效分离系数为萃取体系槽级中的最小有效分离系数．

| Abstract: | Taking the state equation of cascade-extraction system for multi-component RE as basis. tile equivalent separation coefficient is adopted and the multi-component cascade -extraction system is described as equivalent double - component separation system with modified separation (coefficient. The calculation method for equivalent separation coefficient is presented and process design is made with respect to the multi -component casaoe -es traetion separation. Computer analog results show that the equivalent separation eoefficent is the minimun effective separation'coefficient from the extraction banks. |
