Per-and polyflouralkyl substances, otherwise known as PFAS, are a class of chemicals that include perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS). This class of chemcials has a large variety of uses globally, but their utilization has begun to wane due to toxicological concerns and their environmental persistance. As such, remediation of PFAS has gained increasing attention from regulatory and funding agencies. This research study gives a preliminary overview of a water pretreatment system which combines the use of a novel, nanostructured sorbent for the effective removal of PFAS by levereging the material’s selective adsorption and solar light-driven photocatalytic properties. At the heart of the technology are our innovative, chemically stable, metal- organic frameworks (MOFs) which can be tailored for selective PFAS and PFOS capture and host degradation under light irradiation. This novel water treatment solution brings the advantages of high PFAS adsorption capacity in MOFs alongise of the photocatalytic properties of their constituent components.
