Abstract:

Composite purification material is a novel system, which combined selective adsorption capability derived from adsorbent with selective separation property obtained form membrane. Simulate enzyme/emulsion liquid membrane(ELM) composite systems were prepared to hydrolyze tristearin according to the metabolism of glycerides. Two kind of simulate enzyme were used and compared. The experimental results showed histidine is a good simulate enzyme and can effectively extract tristearin under nearly neutral pH value. The apparent degree of removal was 0.03 by this histidine/ELM composite system.

Key words: Histidine, Emulsion liquid membrane, Composite purification material, Tristearin
