Removal method of iodine mixtures from aqueous solution

TLDR: In this article, a method for eliminating an iodine mixture from an aqueous solution is provided to effectively remove the iodine without a separate oxidation or reduction reaction process for making the iodine mixture into a single ion state and to completely eliminate the iodine from radioactive waste liquid.

Abstract: PURPOSE: A method for eliminating an iodine mixture from an aqueous solution is provided to effectively remove the iodine without a separate oxidation or reduction reaction process for making the iodine mixture into a single ion state and to completely eliminate the iodine from radioactive waste liquid. CONSTITUTION: A method for eliminating an iodine mixture from an aqueous solution includes a step of adsorbing a mixture selected from iodide ion(I^-), iodate ion(IO3^-) and iodine using an adsorbate selected from activated alumina, the activated alumina in which Ag are dipped, and activated charcoal. The method comprises the following steps: a step of absorbing the iodate ion from acidic activated alumina and the acidic activated alumina in which Ag are dipped; step of absorbing the iodide ion selected from basic activated alumina and the basic activated alumina in which Ag are dipped; and a step of absorbing the iodine using the activated charcoal.
