| Abstract: | In this paper,on the basis of transfer machanism of L phenylalanine in emulsion liquid membrane system,the extraction and contra extraction were studied during liquid extraction process.The Formula A T] i/A T] e=Cl -] i(K a′ +H +] i)/Cl -] e(K a′ +H +] e) was derived when the whole system was ended,the dominating effects of L phenylalanine extraction were studied using TOMAC as a Carrier,amino acid was extracted and concentrated successfully. |
