<p>TITLE IODINE REMOVAL FROM A GAS PHASE INVENTOR Andreas Ch. Vikis Iodine, usually at least partially in the form of organic iodides, can be removed from a gas phase by irradiating the gas with radiation selected to photodecompose the iodides present until organic iodides have photodecomposed to elemental iodine, providing that ozone is present in the gas phase and reacting all iodine with ozone to form solid iodine oxides which separate from the gas phase. If no organic iodides are present, the initial photodecomposition can be omitted, Where the gas phase contains oxygen the ozone can be generated photochemically in situ. Alternatively, the ozone can be generated separately and fed to the gas phase reaction zone. The method has application to removing radioactive iodine from air and other gases.</p> |
