Abstract
$^{129}I$ is especially one of the most harmful radioactive elements because of its long half-life ($t_{1/2}$=$1.7{\times}10^7$ yr). The efficient removal of iodide ($I^-$) and iodate (${IO_3}^-$) 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.
Keywords
