Porous Organic Materials for Iodine Capture and Radioactive Waste Removal
This community develops porous organic materials, including covalent organic frameworks, metal–organic frameworks, and conjugated microporous polymers, to capture iodine from gas streams and aqueous solutions, primarily for the management of radioactive waste.
The research focuses on designing high-capacity adsorbents that efficiently remove volatile iodine, methyl iodide, and radioactive iodine from air and water. Key materials include covalent organic frameworks, porous organic polymers, activated carbons, and metal–organic frameworks, often functionalized with nitrogen-rich groups to enhance binding. The work addresses the specific challenge of capturing iodine in both vapor and aqueous phases, with a strong emphasis on materials that offer high selectivity, chemical stability, and reversible uptake for potential regeneration.
The largest share of the community's output is found in iodine research, accounting for 1.9% of all iodine research, and 3,015 papers here.
The community comprises 4,282 papers, publishing most frequently in Chemical Engineering Journal, Separation and Purification Technology, and Inorganic Chemistry.
Recent work continues to explore new material classes, including aerogels, lignin-based nanocomposites, and charged adsorbents, for the capture of radioactive iodine and the removal of iodine from wastewater.
