ABSTRACT:
The present process is designed for removing elemental iodine and iodide ions from an aqueous solution containing iodine and iodide ions. This process employees a strong-base anion exchange resin. The resin comprises trialkyl amine groups each preferably comprising from alkyl groups containing 3 to 8 carbon atoms. The aqueous solution containing elemental iodine and iodide ions is passed through the resin and thereby treats the aqueous solution by removing elemental iodine and iodide ions therefrom. The volume of the aqueous solution passing through the resin until reaching the Breakthrough Point is at least about 8 liters per cubic centimeter.
