Abstract	Removal and recovery of bromide ions by electro-oxidation and electro-reduction are presented using hybrid physical adsorption and capacitive deionization cells, which contain activated carbon cloth electrodes. This is a proof of concept research with results, which indicate that when comparing the removal and recovery quantities of bromide and chloride ions (starting with the same initial concentration of 0.05M for both salts), the desalination capacity of the bromide ions is larger by almost two orders of magnitude than that of the chloride ions; thus, we obtained specific desalination of bromide ions from a solution containing chloride ions. Removal and recovery of 3.5 mmoles of bromide ions were achieved by a working electrode with 1 gr of activated carbon cloth, and the calculated energy consumption for the removal and recovery of 1 gr of bromide ions was about 2.24 kJ/gr.

The bromine atom has a radius of 102 pm and its Van der Waals radius is 183 pm. In its elemental form, bromine has a red-brown appearance. Bromine does not occur by itself in nature; it is found as colorless soluble crystalline mineral halide salts. Bromine was discovered and first isolated by Antoine Jérôme Balard and Leopold Gmelin in 1825-1826.
