Résumé
PFAS, or per- and polyfluoroalkyl substances, have received considerable attention due to their persistence in the environment and potential health risks. To address this problem, adsorption has emerged as an effective method for removing PFAS compounds from water. This review provides a comprehensive analysis of various adsorbents used for PFAS removal, including activated carbon, ion exchange resins, clay, and emerging materials such as covalent and metal-organic framework adsorbents. The effectiveness of these adsorbents in removing PFAS compounds is discussed, along with the factors influencing their adsorption, such as pH, competitive matters, and temperature.
Understanding the adsorption behavior of per- and poly-fluoroalkyl substances (PFAS) is crucial for developing efficient removal technologies and mitigating their environmental impact. Several different types of adsorbents are commonly used to treat PFAS in water. Highlighting their advantages and limitations is crucial for improving their design and synthesis to enhance their adsorption performance. image
