Radioactive iodine, a high-yield fission product of nuclear reactions, poses serious environmental and health risks. However, the lack of efficient adsorbents makes the management of aqueous radioactive iodine pollution a significant challenge. N-doped materials are among the most recognized adsorbents for iodine removal, but their weak binding affinity and limited number of iodine-binding N-sites hinder their practical application. Herein, a covalent organic framework (COFs) named phen-TPA is synthesized, featuring an increased number and optimized local chemical environment of iodine-binding N-sites. This material demonstrates record-breaking iodine removal kinetics, withAdvanced science (Weinheim, Baden-Wurttemberg, Germany)Local Charge Density Enhancement Strategy in Nitrogen-rich Covalent Organic Framework for Boosted Iodine Removal From Water.PMC12376611U2167220223278072236601322365012KJRC2023B01YSPTZX2023162023YFC2809000ZDYF2024SHFZ066U23A20104Wang NPan JRong HLiu LCao XZhang JZhang YMa YLiu TYuan YfalseLocal Charge Density Enhancement Strategy in Nitrogen-rich Covalent Organic Framework for Boosted Iodine Removal From Water.The leakage of nuclear pollution highlights the critical importance of effectively separating radioactive pollutants.
