Hierarchical Magnetic Nanocomposite for the Efficient Sequestration of Perfluorooctanoic Acid and Toxic Metals: Unraveling Multimodal Adsorption Mechanisms
Adsorbents that remove per- and polyfluoroalkyl substances (PFAS) alongside heavy metals typically fail because PFAS capture requires acidic pH while metal capture requires near-neutral pH, and materials optimized for one class perform poorly on the other. We report a magnetically recoverable nanocomposite, Fe3O4@SiO...
