Abstract

A method for selective separation of an iodine ion, characterized in that an iodine ion is selectively separated from an aqueous solution containing the iodine ion by the electrodialysis method. The method allows the preparation of a solution containing selectively an iodine ion as an alkali salt without the step of isolating iodine, reduce the number of steps required for obtaining an iodine ion as an alkali salt, and eliminates the need for the use of an auxiliary raw material and for the treatment of a by-product, which results in the production of an alkali salt of an iodine ion with improved efficiency and at a reduced cost.
