At the production of alkali metal chlorate by electrolysis of an electrolyte containing alkali metal chloride in an electrolyzer, impurities of silicon are removed by precipitation with iron ions. Preferably, Fe(II) and/or Fe(III) can be employed as the iron ions. The iron ions can be added either to the electrolyte or to an aqueous solution of the alkali metal chloride. |
