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.
