Recent literature has seen a significant surge in studies focusing on new adsorbent materials for per- and polyfluoroalkyl substances (PFASg), class of contaminants found natural waters worldwide that pose considerable threat to human environmental health. Despite growing interest, the fundamental mechanisms PFAS adsorption these are not fully understood, thus hindering progress developing effective solutions removal. This Review aims bridge knowledge gap by offering critical appraisal recent innovations specifically designed treating PFAS. Strategies aimed at enhancing nanopore capacity or introducing anion-exchange capabilities have shown promise. Innovative such as carbon nanotubes, graphene, graphene oxide evaluated. Modified clay-based silica-based adsorbents demonstrated efficacy removing PFAS, driven hydrophobic effect, Coulombic interactions, electrostatic interactions. Polymers, ranging from types synthetic variants, promise removal across wide pH range. We discuss including F–F ion-pair adsorption, ion exchange chemically thermally modified provide general guideline design adsorbents. offers holistic view advances related materials.

New Insights into Thermal Degradation Products of Long-Chain Per- and Polyfluoroalkyl Substances (PFAS) and Their Mineralization Enhancement Using Additives

The products of incomplete destruction (PIDs) per- and polyfluoroalkyl substances (PFAS) represent a substantial ambiguity when employing thermal treatments to remediate PFAS-contaminated materials. In this study, we present new information on PIDs produced in both inert oxidative environments from five long-chain PFAS, including three now regulated under the U.S. Safe Drinking Water Act, one cationic precursor compound, C10 PFAS. data did not support generation tetrafluoromethane any studied carbonyl fluoride was found only potassium perfluorooctanesulfonate (K-PFOS) heated air narrow temperature range. Oxidative conditions (air) were observed facilitate PFAS degradation accelerate mineralization K-PFOS. Spectroscopic suggest that is initiated by cleavage bonds form perfluoroalkyl radicals, leading organofluorine (e.g., perfluoroalkenes). air, radicals react with oxygen oxygen-containing PIDs. enhanced adding solid additives, which categorized as highly effective granular activated carbon (GAC) certain noble metals), moderately effective, noneffective. Remarkably, simply GAC, achieved >90% perfluorooctanoic acid at 300 °C ∼1.9 atm within just 60 min without using water or solvents.
