A BASIC program has been written for calculating the solute concentrations in phases in different stages under given conditions of fractional extraction by iteration method. The optimization process of Tbseparation was selected with the aid of established objective function by direct Seeking method. The mathematical simulation was verified by comparison with experimental one. The relative error of the purity for Tb or Dy<1.6% and of recovery<4.5%. Thus, a mathematical simulation method of modelling the extraction equilibria, simulating the steady state feature of fractional extraction and selecting the optimization process may be available for the extraction separation of any binary metal. 收稿日期: 1983-01-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 沈韵玉 应娓娟 雅文厚 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1983/V19/I1/101 1 雅文厚;沈韵玉,金属学报,19(1983) ,B12． 2 Goto, T., Solvent Extraction, Proc. of the Int.
