文摘
- •
PFOA is oxidized by heat-activated persulfate within 72 h at 50 °C.
- •
PFOA persulfate oxidation follows an unzipping pathway to PFCAs and fluoride.
- •
PFOA transformation rates increases with increasing temperature.
- •
Heat-activated persulfate oxidizes 6:2 FTSA simultaneously to PFHpA and PFHxA.
- •
PFOS is not transformed with heat (85–90 °C)-activated with persulfate (60–84 mM).
