Abstract: PURPOSE: A method for removing iodine ion, iodic acid and iodine from an aqueous solution and waste water is provided which is useful for treating waste water from iodine related industries and various atomic industries. CONSTITUTION: The method comprises by a)changing iodine ion(I¬-) or iodic acid(IO¬3), or all together from aqueous solution or waste water containing one or more selected from iodine ion(I¬-), iodic acid(IO¬3) and iodine(I¬2) to iodine(I¬2) and b)absorbing the obtained iodine(I¬2) and the originally existing iodine(I¬2) by activated carbon. For an example, 100 ml of aqueous solution containing 5 mg/L of each iodine ion(I¬-), iodic acid(IO¬3) and iodine(I¬2) is added with 1N hydrochloric acid to adjust its concentration to pH3, added with 17.2 ml of potassium iodide, 1 g of activated carbon, held for a fixed time, and filtrated by a glass filter. The test shows that the concentration of iodine ion(I¬-) and iodic acid(IO¬3) is below 0.1 mg/L and the concentration of iodine(I¬2) is below 0.05 mg/L. The method can remove all kinds of iodine mixtures regardless of a mole ratio of iodine ion and iodic acid and applied to a general industrial field dealing with iodine, including the treatment of radioactive wastewater from various atomic industries.
