Synergistic and Complementary Electrostatic and Hydrophobic Interactions Drive Per- and Polyfluoroalkyl Substance (PFAS) Adsorption to Cationic β-Cyclodextrin Polymers.
Styrene-functionalized β-cyclodextrin (StyDex) polymers are structurally tunable adsorbents for removing per- and polyfluoroalkyl substances (PFASs) from water. Although specific functional elements are included in StyDex polymers to enhance PFAS adsorption, their relative contributions are not well understood. This kn...
