(57) [Summary] [Purpose] It can contain a large amount of silver salt or a unit of silver, and can prevent the wear of silver bound by radioactive iodine and the resulting serious damage to, for example, a reprocessing facility. A possible organic-based iodine adsorbent is provided. An iodine adsorbent containing silver or a silver salt on a porous, temperature and acid stable inorganic carrier, the adsorbent having a mesopore diameter range of 6 to 200 nm, It has a pore diameter distribution such that 80% of the pore volume is contained within pores having pore diameters within the range of ± 50% of the mesopore diameter. |
