Abstract
An oxidizing resin for iodide conversion and retention is prepared from a metal chelating resin providing functional groups binding polyvalent metal ions. The oxidizing resin is formed by applying an alcohol solution of zirconium peroxide to the chelating resin granules. The resulting oxidizing resin will convert iodide to iodine in aqueous solution, and will retain the converted iodine within the resin granules. When the oxidative capacity has been reduced by treating large amounts of iodide, it can be easily regenerated by contacting the zirconium-containing resin with hydrogen peroxide.
