【Abstract】 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.更多还原
