Metal-Organic Framework Featuring Monodispersed Silver Cation Sites for Highly Efficient and Selective Extraction of Aqueous Iodide Anions.

ABSTRACT: Efficient extraction of iodide ion (I^-), the dominant form of aquatic iodine, is crucial for both resource recovery and pollution mitigation, particularly in seawater, nuclear wastewater, and drinking water. However, this remains a significant challenge due to the lack of adsorbents that simultaneously offer high affinity, fast kinetics, and reliable reusability for I^- capture. Herein, a novel cationic metal-organic framework featuring monodispersed silver (Ag⁺) sites (MOF-monoAg), which outperforms conventional Ag-loaded materials that rely on post-synthetic loading, enabling uniformly dispersed and highly accessible binding sites for selective and efficient I^- extraction, is presented. The unique Ag⁺ sites exhibit extraordinary bindi
