The potential consequences of radioactive iodine motivate the development of highly effective adsorbents with facile synthesis strategies. Pyrrolidinone was herein employed as the monomer to prepare hypercrosslinked polymers (HCPs) via a simple Friedel-Crafts reaction catalyzed by FeCl3. Owing to the affinity sites of pyrrolidinone toward iodine, high surface area, and electron-rich aromatic networks of HCPs, the developed pyrrolidinone-based HCPs exhibited an iodine uptake capacity up to 460 wt%. Our work highlighted new opportunities in using HCPs as a platform for iodine capture from nuclear waste for environment remediation by taking advantages of their facile synthesis and low cost.
