ABSTRACT:
Process for the purification of an aqueous alkali metal chloride solution from iodine compounds and ammonium compounds, in which the operation is carried out in two successive stages comprising a first stage in which the iodine compounds are oxidized to molecular iodine which is removed from the solution on a halogenated basic anion exchange resin, and a second stage in which the ammonium compounds are oxidized to form nitrogen which is removed in a stream of inert gas.
