(a) Parent compound decay and (b) defluorination of n = 1–7 PFCAs by UV/S (10 mM), and UV/S (10 mM) + I (2 mM). Panel (c) shows the magnified defluorination profiles for n = 2–7 PFCAs (averaged) within the first 1 h. (d–f) Parent compound decay and defluorination of n = 4, 6, 8 PFSAs. Reaction conditions: individual PFAS (0.025 mM), NaHCO3 (5 mM), pH 12.0, 254 nm irradiation (an 18 W low-pressure Hg lamp in 600 mL solution), and 20 °C.
