Anion exchange resins (AERs) have been widely used for the removal of perfluoroalkyl and polyfluoroalkyl substances (PFAS) from water. However, regardless whether AERs are regenerable or single use, disposal end-of-life presents significant challenges. Conventional waste management strategies, such as landfill incineration, increasingly under scrutiny may face impending bans due to environmental concerns. This study introduces a nonthermal, solvent-free process effective destruction PFAS on by co-milling piezoelectric boron nitride (BN) powders with contaminated stainless steel (SS) balls. The approach achieved complete PFOS in two types (PFA694E AmberLite IRA 67), near-quantitative (∼100%) defluorination observed treatment PFA694E AER. Comprehensive targeted analysis suspect screening transformation products (TPs) elucidated reaction mechanisms confirmed that functional groups did not participate reaction. process's effectiveness was further validated treating field-collected single-use (PFA694 PSR2 Plus) mixtures varying chain lengths head groups. After treatment, levels were reduced below nanogram per gram detection limits, no release standard leaching tests.

Electrosorption (ES) is a research frontier in electrochemical separation, with proven potential applications desalination, wastewater treatment, and selective resource extraction. However, due to the limited adsorption capacity of film electrodes, ES requires short circuiting or circuit reversal, accompanied by solution switch between feed receiving solution, sustain desalination over many charge-discharge cycles. In previously reported studies, switches have been commonly ignored simplify experimental procedures, their impacts on separation performance are thus not well understood. This study aims provide quantitative analysis mixing ES-based desalination. A numerical model has employed evaluate adverse effects three used operation modes. The reveals that solution-switch more severe larger concentration difference desalinated water brine provides insights into effectiveness increasing electrode loading specific mitigating detrimental mixing. Even state-of-the-art systems, producing freshwater from seawater even brackish medium-to-high salinity practically challenging presence switch.
