Also provided are methods for making the electrodes and methods for using the electrochemical cells to remove chloride ions from a sample. The chloride-storage electrodes, which are composed of bismuth metal, can store chloride ions in their 0 bulk by forming BiOC1 via an oxidation reaction with bismuth in the presence of an oxygen source.
