The nuclear industry will continue to develop rapidly and produce energy in the foreseeable future; however, it presents unique challenges regarding the disposal of released waste radionuclides because of their volatility and long half-life. The release of radioactive isotopes of iodine from uranium fission reactions is a challenge. Although various adsorbents have been explored for the uptake of iodine, there is still interest in novel adsorbents. The novel adsorbents should be synthesized using reliable and economically feasible synthetic procedures. Herein, we discussed the state-of-the-art performance of various categories of porous organic materials including covalent organic frameworks, covalent triazine frameworks, porous aromatic frameworks, porous organic cages, among other porous organic polymers for the uptake of iodine. This review discussed the synthesis of porous organic materials and their iodine adsorption capacity and reusability. Finally, the challenges and prospects for iodine capture using porous organic materials are highlighted.
在可预见的未来，核工业将继续快速发展并生产能源；然而，由于释放的废放射性核素具有挥发性和长半衰期，其处置面临独特挑战。铀裂变反应中碘放射性同位素的释放是一个挑战。尽管已探索了各种吸附剂来摄取碘，但对新型吸附剂仍有兴趣。新型吸附剂应采用可靠且经济可行的合成方法来合成。在此，我们讨论了各类多孔有机材料（包括共价有机框架、共价三嗪框架、多孔芳香框架、多孔有机笼以及其他多孔有机聚合物）在摄取碘方面的最新性能。本综述讨论了多孔有机材料的合成及其碘吸附容量和可重复使用性。最后，强调了使用多孔有机材料捕获碘所面临的挑战和前景。
