Abstract
A device for removing chloride-containing salts from water includes a container configured to contain saline water, a first electrode arranged in fluid communication with the saline water, and a power source. The first electrode includes a conversion material that is substantially insoluble in the saline water and has a composition that includes at least two or more of aluminum, chlorine, copper, iron, oxygen, and potassium. The composition varies over a range with respect to a quantity of chloride ions per formula unit. The power source supplies current to the first electrode in a first operating state so as to induce a reversible conversion reaction in which the conversion material bonds to the chloride ions in the saline water to generate a treated water solution. The conversion material dissociates the chloride ions therefrom into the saline water solution in a second operating state to generate a wastewater solution.
