谷氨酸在乳狀液膜中的遷移行為

谷氨酸在乳狀液膜中的遷移行為

摘要： 用氯化三辛基·甲基銨(Aliquat 336)?Span80?甲 苯制成的乳狀液膜體系對谷氨酸的遷移行為進行了研究，2 min的遷移率可達93%。在谷氨酸的最佳遷移條件下，油溶性好的苯丙氨酸遷移率較高，但油溶性低的甘氨酸和堿性氨基酸的遷移率明顯較低。此法適用于微量氨基酸的提取和分離。 Abstract： The transport of glutamic acid through the surfactant liq uid membrane of trioctyl (mono) methyl ammonium chloride(Aliquat336)?Span 80-toluene has been studied. The optimal experimental conditions for transport of gl utamic acid with high efficiency and high speed were obtained. The conditions we re that membrane phase was 0.020 mol/L Aliquat 336+3%(?W／V?）Span80+Tolu ene; Outer phase was 5×10-4 mol/L glutamic acid and Ph=9.3；Inner pha se was 0.05 mol/L HCl. The transport rate of glutamic acid reached 93% in 2 min of transport time. The phenylalanine was also transported at the optimal transpo rt conditions of glutamic acid. The transport rates of Glycine and basic amino a cids were lower. This method can be used for extraction and separation of micro amount of amino acids. 作 者： 鄒長英    張紅    徐變珍    Zou Changying    Zhang Hong    Xu Bianzhen   作者單位： 鄒長英,徐變珍,Zou Changying,Xu Bianzhen(山西職工醫學院,)
