As the mole fraction of TbCl_3, x_A=0.10—0.92, the acidity, x_B =1.1—3.4 mol·kg~(-1), and the total rare earth concentration, x_C=0.03—0.96 mol·kg~(-1), in the aqueous solution, the correlation coefficient of the model would be 0.9957, the average error would be 3.22% and the average error of the predictive value would be ±3.01%. The β_(Dy/Tb) was 2.69±0.056 as obtained from the experiments.From the results calculated by the model, the extraction equilibrium lines with the rare earth concentrations, acidities and mole fraction were drawn. Discussions were given.The TbCl_3-DyCl_3 model may be used for the stagewise calculations and for designing the corresponding extraction separation procedures. 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 雅文厚 沈韵玉 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1983/V19/I1/94 1 沈韵玉;雅文厚;应娓娟,稀有金属,3(1979) ,15． 2 Peppard, D.
