METHOD FOR RENDERING IODINE FLUORIDE HARMLESS

摘要

Disclosed is a method for rendering iodine fluoride harmless, which is characterized in that a reagent, which contains not less than 5% by mass but not more than 100% by mass of an alkali metal oxide, an alkali metal carbonate, an alkaline earth metal carbonate, an alkaline earth metal, an alkaline earth metal oxide, an alkali metal hydroxide or an alkaline earth metal hydroxide in total, is brought into contact and reacted with a gas, which contains iodine fluoride represented by the following general formula: IFx (wherein x represents 1, 3, 5 or 7) at a concentration not more than 10 vol%, at a temperature of not less than 0°C but not more than 540°C, so that the iodine component and the fluorine component are immobilized on the reagent.  By this method, iodine fluoride can be efficiently rendered harmless.
