Radioactive iodine (I) with a short half-life of ~8.02 days is one of the most commonly used nuclides in nuclear medicine. However, I easily poses a significant risk to human health and ecological environment. Therefore, there is an urgent need to develop a secure and efficient strategy to capture and store radioactive iodine. Metal-organic frameworks (MOFs) are a new generation of sorbents with outstanding physical and chemical properties, rendering them attractive candidates for the adsorption and immobilization of iodine. This review focuses on recent research advancements in mechanisms underlying iodine adsorption over MOFs and their derivatives, including van der Waals interactions, complexing interactions, and chemical precipitation. Furthermore, this review concludes by outlining the challenges and opportunities for the safe disposal of radioactive iodine from the perspective of the material design and system evaluation based on our knowledge. Thus, this paper aims to offer necessary information regarding the large-scale production of MOFs for iodine adsorption.
半衰期约为8.02天的放射性碘（I）是核医学中最常用的核素之一。然而，碘很容易对人类健康和生态环境构成重大风险。因此，迫切需要制定一种安全有效的策略来捕获和储存放射性碘。金属有机框架（MOF）是新一代具有出色物理和化学性质的吸附剂，使其成为吸附和固定碘的有吸引力的候选材料。本综述重点关注MOF及其衍生物对碘吸附的潜在机制的最新研究进展，包括范德华相互作用、络合相互作用和化学沉淀。此外，本综述基于我们的知识，从材料设计和系统评估的角度概述了安全处置放射性碘的挑战和机遇，从而得出结论。因此，本文旨在提供有关大规模生产用于碘吸附的MOF的必要信息。
