Destruction of PFASs by UV/Sulfite/Iodide Advanced Reduction Process

PFAS (per- and polyfluoroalkyl substances) encompass a large and diverse group of chemicals known for their robustness and persistence, leading to significant environmental persistence and bioaccumulation concerns. Photochemical treatments, particularly those utilizing UV light to generate hydrated electrons, are at the forefront of emerging technologies aimed at effectively breaking down PFAS compounds. These UV-based processes typically involve the generation of, which are highly reactive and can effectively reduce PFAS by breaking the strong C-F bonds characteristic of these compounds. This method shows potential not only in degrading PFAS but also in achieving this without producing equally harmful secondary pollutants, a common issue with other remediation techniques.
