A desalination device includes a container, first and second electrodes, an anion exchange membrane (AEM), and a power source. The container contains saline water that has an elevated concentration of dissolved salts. The AEM separates the container into first and second compartments into which the first and second electrodes, respectively, are arranged. The AEM has a continuous porous structure and a plurality of negatively-charged oxygen functional groups coupled to the porous structure. The power source is configured to selectively apply a voltage to one of the first and second electrodes.
