Abstract
Compositions for bromide removal include a two-dimensional material impregnated with silver. The silver may be impregnated in the two-dimensional material by contacting the two-dimensional material with silver ions in an aqueous solution, allowing the silver ions to adsorb on the two-dimensional material, and drying the two-dimensional material. Removing bromide from an aqueous composition including bromide may include contacting the aqueous composition with a two-dimensional material impregnated with silver, and allowing the bromide to react with the silver to yield silver bromide.
