In this study, we prepared iodinated resins from the anion-exchange resins and examined about its effectives of the iodine release and sterilization. The sterilized experiments were operated by transit of underground water in the column filled with iodinated resins. Its results were as follows. Amounts of iodine releases were showed under injurious concentrations of body. Its sterilized effectives showed better A-520-E iodinated resin than IONACⓡASB-2 HP. In short, A-520-E iodinated resin showed effective sterilization and amount of release iodine under injurious concentration of body, so this iodinated resin was compatible for edible water.
