The Improvement of Determination Method of Sodium Salt Content in Gulonic Acid 测定维生素C过程产物中钠盐含量的方法改进
In this paper, a new ultrafiltration pilot-Sun flo membrane separation system was used to extract gulonic acid from Vitamin C fermentation liquor that was not pretreated. The quality of filtrate was high and the filtering yield was as high as 99.24%. 采用超滤膜分离新设备&Sun-flo超滤膜分离系统一步截留不经预处理的维生素C发酵液中的菌丝体、蛋白质和悬浮的固体颗粒等杂质,滤液质量高,过滤收率高达99.24%。
