Development of a photocatalysis method for oxidative conversion of unknown PFAS into measurable species for assessment of total PFAS in food and environmental samples including drinking water

The project addresses the challenge of assessing the extensive group of per- and polyfluoroalkyl substances (PFAS). With over 4700 known chemicals, only a few are monitored due to practical limitations. The goal is to develop a method for indirect quantification using photocatalysis to oxidatively convert both known and unknown precursor compounds into measurable PFAS in food and water. This approach aims to surpass the limitations of current methods, like persulfate-activated hydroxyl radical oxidation, and enhance performance, especially in challenging matrices such as foods and wastewater.
