| Abstract: | Based on advancing front model, a mass transference model of unsteady state for extraction of PG by the emulsion liquid membrane was developed. Under experimental conditions, the extraction rate of penicillin G might be controlled by the diffusion process and the diffusion resistance exists mainly in the membrane phase. Namely, the diffusion step of penicillin G in the membrane phase might be the controlling step. |
