摘要:

依据甘油三酯在体内的代谢过程,将组氨酸作为模拟酶,与液体石蜡-Span 80乳状液膜体系复合,制备具有双重选择性的复合血液净化材料,并对其主要影响因素进行了研究.对三硬酯酸甘油酯的清除实验表明,该复合体系在30min内,即可有效清除目标物,表观清除率可达0.03.

关键词: 组氨酸, 乳状液膜, 复合净化材料, 三硬酯酸甘油酯

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
