电渗析法分离中性有机物、强酸和弱酸的实验研究

Test of Electrodialysis Separation of Neutral Organic Compound, Strong Acid and Weak Acid

采用阳膜和复合膜组成的电渗析装置成功地将乙二醛、硝酸和醋酸各个分离并回收,从而取代萃取法工艺.解决了萃取工艺工序多,运行费用大,废液(硝酸和醋酸)污染环境的问题。

The electrodialysis device using positive membrane and compound membrane can success-fully separate glyoxal,nitric-acid and acetic-acid respectively. So this device may substituted for the old ex-traction method.
