Abstract
En 中文
With the extensive use of nuclear energy, the disposal of radioactive iodine waste has become an issue in the energy industry. Herein, we reported a series of quadruple hydrogen-bonded supramolecular polymers combining 2-ureido-4[1H]-pyrimidinone (UPy) with Tröger's base (TB) for iodine adsorption: TB-UPys, demonstrated a volatile iodine adsorption capacity of 4 g·g−1, with a second-order kinetic rate constant of 2.8 × 10−4 g·min−1·mg−1 for aqueous iodine adsorption. This work leverages the unique hydrogen bonding properties to construct stable and robust iodine adsorption materials, paving a new way forward for the future development of iodine adsorbents.
