Fabrication of hydrogen-bonded metal-complex frameworks for capturing iodine
In this paper, novel hydrogen-bonded metal-complex frameworks MPM-1-TIFSIX and HOF-21 were selected as adsorbents to adsorb iodine. MPM-1-TIFSIX and HOF-21 were prepared by layering method and mixed stirring method, respectively. The structures of the two HOFs were characterized in detail by XRD , BET, TGA and FT-IR. The adsorption behavior and adsorption capacity of MPM-1-TIFSIX and HOF-21 for iodine were investigated in detail. The experimental data showed that the equilibrium adsorption amounts of MPM-1-TIFSIX and HOF-21 were 205.51 mg/g and 172.86 mg/g, respectively. The adsorption process of MPM-1-TIFSIX was conformed to be pseudo-second-order kinetic, while the adsorption process of HOF-21 was conformed to be pseudo-first-order kinetic. The results indicated that HOFs could be used as iodine capture and storage materials.
