| 摘 要： | 在确定极限电流密度的前提下,测定了氨基酸盐溶液在电渗析过程中,不同淡水流速和浓度对脱盐率及氨基酸回收率的影响,得出了最佳操作参数。同时,通过模拟γ-氨基丁酸(GABA)发酵液的组成,分别配制了乳酸和葡萄糖模拟发酵液,从而测定了发酵液中其他物质的存在对电渗析过程的影响。

| Abstract: | After the determination of the limiting current density,The influences of different flow rate and different concentration on the desalting rate and the recovery of amino acid in the electrodialysis desolation of the amino acid solution were measured,the best operation parameters were determined.Meanwhile,by simulating the fermentation of Gama-aminobutyric acid(GABA),the lactic acid and the glucose simutation fermentation were made separated,the influences of other substance in the fermentation on the electrodialysis were measured. |

| Keywords: | electrodialysis limiting current density the desalting ratio the recovery of amino acid |
