Abstract
A method is provided for removing iodide from aqueous solutions in which the iodide is converted to iodine. The porous granules of the polyvalent metal chelating resin containing zirconium peroxide bound to the chelating groups thereof is contacted with the aqueous iodide solution. The iodine is formed within the granules and retained therein, permitting the aqueous solution to be separated to create iodine. This iodine can be recovered by organic solvent elution. The oxidative capacity of the resin granules has been reduced, it can be regenerated after removal of the obtained iodine by contacting the resin granules with aqueous hydrogen peroxide.
