Abstract
|
|
|
129I is especially one of the most harmful radioactive elements because of its long half-life (t¨ö=1.7¡¿107 yr). The efficient removal of iodide (I?) and iodate (IO©ý?) 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.
