Abstract
The present invention relates to a process for recovering copper from solutions from the recovery of iodine from industrial wastes from the production of ionic and non-ionic iodinated X-ray contrast agents by use of chelating resins suitable for removing copper from aqueous solutions. The absorbed copper is displaced by treating the resins with a 10% hydrochloric or sulfuric acid solution.
