| Outline of Final Research Achievements |
In this study, we studied the separation mechanism of anions from aqueous solution by nanoporous carbon materials and required factors for the separation of anions. We found that selective adsorption of anions can be initiated by the formation of adsorbed phase of proton where the surface potential is negative because of the pi-conjugated system of carbon adsorbents. Also, anions can be strongly adsorbed onto the cylindrical nanospace of carbon materials whose pore size is comparable to that of hydrated anions.
