ABSTRACT:
A method is provided for treating drinking water for disinfecting and/or removing iodide. The method utilizes resin bound silver ions. For performing the disinfection or iodide removal with minimal release of silver ions into the water being treated, a chelating resin having iminodiacetic acid chelating groups is employed, and the resin is loaded with not over 0.5 mol of silver ion per mol of iminodiacetate.
