Abstract

The removal of vitamin C from a mixture with 2-ketogluconic acid by using a bulk liquid membrane (BLM) has been investigated. The studies on facilitated pertraction of vitamin C with Amberlite LA-2 indicated the major parameters that affect the separation efficiency: pH gradient between the two aqueous phases, carrier concentration in the liquid membrane and phase mixing intensity. The overall results obtained in this work showed that liquid membrane system can effectively be used to selectively separate vitamin C from its mixture with the fermentation by-product, 2-ketogluconic acid.

摘要

研究了利用支撑液膜（BLM）从与2-酮基葡萄糖酸的混合物中去除维生素C的方法。用Amberlite LA-2促进维生素C渗透萃取的研究表明了影响分离效率的主要参数：两个水相之间的pH梯度、液膜中的载体浓度和相混合强度。这项工作获得的总体结果表明，液膜系统可有效地用于从其与发酵副产物2-酮基葡萄糖酸的混合物中选择性分离维生素C。
