This work tested an effective and efficient Nd/La extraction and separation via flat-sheet supported liquid membrane. A microporous polypropylene film was used as the solid support for the liquid membrane and P507 as the extractant. The effect of Nd(III) and La(III) concentration in the feed, the concentration of P507, and acid solution concentration in the stripping phase on Nd and La extraction and separation were studied. The results suggest the extraction of La and Nd increases with the initial pH of the feed solution and P507 concentration. Maximum separation factor of 44.25 was obtained at the low P507 concentration of 5% (v/v).

以 EHEHPA (P507) 为载体的负载型液膜高效分离 Nd(III) 和 La(III)

这项工作通过平板支撑液膜测试了一种有效且高效的 Nd/La 萃取和分离方法。微孔聚丙烯薄膜用作液膜的固体载体，P507 用作萃取剂。研究了进料中Nd(III)和La(III)浓度、P5O7浓度和反萃取相酸溶液浓度对Nd和La萃取分离的影响。结果表明，随着进料溶液的初始 pH 值和 P5O7 浓度的增加，La 和 Nd 的提取量增加。在 5% (v/v) 的低 P507 浓度下获得了 44.25 的最大分离因子。
