摘要
本文以TOMAC为载体.ECA4360J为表面活性剂.内外相Cl^-浓度梯度为推动力,研究了L-苯丙氨酸在乳状液膜体系中的传输,并对影响液膜萃取的各种因素进行了系统的阐述,确定了此体系的最佳膜相组成和实验条件,实现了L- 苯丙氨酸的提取和浓缩.
In this paper, the transport of L-phenylalanine in emulsion liquid membrane system containing TOMAC as a carrier, ECA4360J as a surfactant and Cl-1 concentration gradient between interior and exterior phase as driving force was studied. The various factors affecting extraction in emulsion liquid membrane system were investigated and explained systematically. The suitable conditions and the best membrane formulation were established , amino acid was extracted and concentrated successfully.
