Breaking the Perfluorooctane Sulfonate Chain: Piezocatalytic Decomposition of PFOS Using BaTiO3 Nanoparticles

Creators

Description

Per- and polyfluoroalkyl substances (PFAS) pose significant environmental andhealth risks due to their ubiquitous presence and persistence in water systems.Herein, the efficacy of piezocatalysis using barium titanate nanoparticles underultrasound irradiation for the degradation and defluorination of perfluorooctanesulfonate (PFOS) in water is investigated. The research demonstrates a sub-stantial 90.5% degradation and 29% defluorination of PFOS after 6 h of treat-ment, highlighting the potential of piezocatalysis as a promising approach forPFAS degradation. Additionally, the quantification of degradation productselucidates the transformation pathways of PFOS, suggesting a stepwise chain-shortening mechanism. The findings underscore the importance of continuedresearch in optimizing piezocatalytic processes and exploring synergisticapproaches with other advanced oxidation methods to effectively address PFAScontamination challenges. These efforts are essential for advancing sustainablewater treatment strategies and mitigating the environmental and health hazardsassociated with PFAS contamination.
