摘要：

The effects of ageing and incorporation of ion-exchange membrane on the electrosorption performance of activated carbon (AC) electrodes-based electrosorption modules were investigated. It was found that the surface area of aged electrode decreased while the average pore size increased. In addition, more surface functional groups, especially - COOH groups were created on the electrode surface due to ageing. All these lead to a decrease in the electrosorption capacity and electrosorption rate. Incorporation of ion-exchange membranes can improve the desalination performance of the electrosorption module, especially for the aged electrode.
