摘要
采用乳状液膜法分离发醇液中的柠檬酸 ,讨论了该方法的工艺过程 ,对乳水比、油内比、搅拌速率、破乳及油相回用等工艺条件进行了研究。结果表明 ,在 Span- 80 - TOA- Na2 CO3 -煤油所组成的膜体系中 ,选择 Rew=1∶ 2 ,Roi=1∶ 1 ,n=330～ 350 r/min的工艺条件可得到满意的提取结果。
The liquid membane method was applied to the process of separating citric acid from the fermentation liquor, and the technological process of this method, R ew , R oi , stirring speed, demulsification, oil phase reagents retrieving and so on were discussed. The experiment results showed that, a better result can be achieved for the system choosing R ew =1∶2,R oi =1∶1,n=300-350r/min of spen 80-TOA-Kerosene and Na 2CO 3 as liquid membrane composition.
