PFAS (Per- and polyfluoroalkyl substances) adsorption is a research area focused on the removal of these persistent organic pollutants from water and other environmental sources using adsorption techniques. PFAS are a group of man-made chemicals that have been widely used in various industrial and consumer products, leading to their presence in water sources worldwide. Adsorption is a process in which contaminants are physically or chemically removed from a liquid or gas phase by binding to a solid surface. This research area aims to develop effective and efficient adsorbent materials that can selectively capture PFAS molecules from contaminated water, soil, or air. Various materials have been studied for PFAS adsorption, including activated carbon, ion exchange resins, and polymer-based adsorbents. Research in this area also focuses on understanding the mechanisms involved in PFAS adsorption, optimizing adsorbent materials for enhanced performance, and exploring potential applications of adsorption technology in environmental remediation and water treatment processes. Overall, PFAS adsorption research plays a crucial role in developing sustainable solutions for mitigating the environmental and health impacts of PFAS contamination.
