Abstract
Process and plant for the purification of an aqueous alkali metal chloride solution containing iodide ions, according to which the iodide ions are oxidised to iodine by means of active chlorine generated in situ by electrolysis (4) of the solution and the iodine is removed over a basic halogenated anion exchange resin (5). <IMAGE>
