Abstract

129I is especially one of the most harmful radioactive elements because of its long half-life (t½=1.7×107 yr). The efficient removal of iodide (I⁻) and iodate (IO₃⁻) in a aqueous solution by adsorption using activated alumina and activated carbon was studied. The removal efficiency was over 99% for iodide ion with silver treated basic alumina and iodate ion with acidic alumina or silver treated acidic alumina without any chemical addition or physical treatments.
