Engineering an amine-functionalized Zn(<scp>ii</scp>) interpenetrated metal–organic framework for comprehensive iodine uptake across diverse phases and selective azo dye adsorption

Abstract

(25 °C). AR-2 also achieves 89-91% iodine adsorption in aqueous and organic solvents. Remarkably, iodine-loaded AR-2 retains up to 96-97% of its captured iodine at 25 °C, demonstrating its potential for long-term storage and safe transportation of radioiodine. Furthermore, AR-2 selectively adsorbs hazardous azo dyes, such as Bismarck Brown and Methyl Orange, from aqueous solutions, showcasing rapid kinetics, high stability, and reusability. These findings position AR-2 MOF as a promising candidate for environmental remediation, including off-gas filtration and wastewater treatment in nuclear and chemical industries.
