【摘要】 本文研究了液膜提取过程中的萃取和反萃取两个过程，推出了在整个液膜体系达到萃取终了时的内外相氨基酸浓度比公式，并以ＴＯＭＡＣ 为载体萃取Ｌ－ 谷氨酸为例，讨论了影响液膜萃取的控制因素，实现了Ｌ－ 谷氨酸的有效回收更多还原

【Abstract】 In this paper,the extraction and contra extraction were studied during liquid extraction process,the formula [A T] i/[A T] e=[Cl -] n i( K ′+[H +] n i)/[Cl -] n e( K ′+[H +] n e) was derived when the whole system was at the end.the dominating effects of L glu.extraction were studied using TOMAC as a carrier,amino acid was extracted and concentrated successfully.更多还原
