Published: July 25, 2024

Abstract Porous materials are excellent candidates for water remediation in environmental issues. However, it is still a key challenge to design efficient adsorbents rapid purification from various heavy metal ions‐contaminated wastewater one step. Here, two robust nitrogen‐rich covalent organic frameworks (COFs) bearing terpyridine units on the pore walls by “bottom‐up” strategy reported. Benefitting strong chelation interaction between and ions, these COFs show removal efficiency capability Pb 2+ , Hg Cu Ag + Cd Ni Cr 3+ water. These shown remove such ions with >90% of contents at time after aqueous mixture passed through COF filter. The features also endow them capturing iodine vapors, offering potential applications.
