| Abstract: | In this paper, the transport of L-glutamic acid in emulsiony liquid membrane system containing di(2-ethylhexyl)phosphoric acid as a carrier, ECA4360J as a surfactant and H 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 for mulation were established, Amino acid was extracted and concentrated successfully. |
