Efficient Capture of Short‐ and Long‐Chain PFAS from Water by a Metal–Organic Framework
Small, Volume 21, Issue 51, December 23, 2025.A biologically derived metal‐organic framework (MOF) shows rapid and efficient removal and extraordinary reusability of both long‐ and short‐chain PFAS, outperforming conventional adsorbents. With dual hydrophobic‐hydrophilic channels and fast adsorption under continuous‐flow conditions, this MOF enables structural insights via X‐ray diffraction and ...
