摘要(Abstract)：

20世纪70年代,徐光宪教授创建了串级萃取理论,建立了稀土串级萃取工艺的最优化参数计算方法。结合计算机技术,又建立了串级萃取工艺的静态参数设计和动态仿真计算技术,实现了工艺设计参数到工业规模生产应用的"一步放大"。近40年来,串级萃取理论及其计算方法始终引领和支撑着中国稀土分离技术的持续发展,同时,萃取工艺技术和装备的进步也不断地促进了该理论的丰富与完善。理论的适用范围由早期的恒定混合萃取比体系发展到非恒定混合萃取比体系,分离流程由两出口发展到三出口、多出口体系,并进一步发展为多入口、多出口的联动萃取工艺;串级萃取工艺的最优化参数计算方法也由两组份体系拓展至多组分分离体系,从单一工艺优化拓展到稀土全分离流程的整体优化。本文简要综述了串级萃取理论发展中的重要工作与应用情况,深入介绍了联动萃取工艺计算及流程优化等方面的最新进展及应用前景。
