We prepared cation exchange membranes (CEMs) and anion exchange membranes (AEMs) by a heavy-ion-track grafting method, and then used them for seawater electrodialysis process. The concentration of the obtained seawater was higher than that in the case of the commercial CEM/AEM. This result demonstrates our CEMs and AEMs are suitable for this application.
