NOVELTY - Producing iodine adsorption filter, comprises (S110) mixing bismuth graphene oxide produced by reacting graphene oxide with bismuth nitrate, a binder, a thickener, and water to form a coating mixture; and (b) coating the coating mixture on a predetermined filter. USE - The iodine adsorption filter is useful for adsorbing iodine from radioactive waste liquid. ADVANTAGE - The iodine adsorption filter: increases convenience and efficiency in adsorbing iodine from radioactive waste liquid by allowing iodine to be adsorbed by an adsorbent coated on the filter; and easily adsorb and increase the adsorption efficiency at the same time. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating a method for producing an iodine adsorption filter (Drawing includes non-English language text).
