Abstract

Methods for producing or regenerating an iodinated anion exchange resin are presented. The methods include treating an iodide loaded anionic resin with an aqueous solution comprising an in situ formed I2 to produce the iodinated resin. The iodinated resins show reduced and stable levels of iodine elution compared to resins produced by conventional methods. Methods and systems for purifying water are also presented.
