Abstract
The invention provides a method for preparing polyhalide resin disinfectants. The step of the method involves circulating an effective amount of a polyhalide salt carrier solution between an effective amount of elemental halide and a strong base anion exchange resin until substantially all of the resin is converted to the polyhalide form. The elemental halide and the resin are separately disposed but connected so that the polyhalide salt carrier solution can be recirculated until all of the elemental halide is transferred to the resin. The method of the invention can be used to form a tri-iodide or penta-iodide resin, or mixed form of the resin including IBr.sub.2.sup.-/I.sub.2.sup.-.
