摘要
研究用壳聚糖膜的电渗析法分离水溶液中的氟、氯和砷负离子 .在一定的酸度条件下 ,可将溶液中的 F-、Cl-和 As O- 2 除去 .实验考查了电压、酸度和浓度等条件的影响 ,得到了最佳的分离条件 .研究表明 ,壳聚糖膜电渗析法分离氟、氯和砷的在 2 0 0 mg· L- 1。
F -、Cl - and AsO - 2 in aqueous solution were separated by the electrodialysis method using chitosan membrane.The effect of experimental conditions,such as voltage,acidity and concentration was examined.The results showed that the chitosan membrane can be used to separate F -,Cl - and AsO - 2 by eletradialysis method.It is important to control experimental conditions.
