A) Library of Ionic Fluorogels. ^a Calculated by Differential Scanning Calorimetry during the second heating cycle at a rate of 10 °C/min. ^b Ratio of swollen to dry mass of IF after swelling in 0.1 M NaCl. B) Batch equilibrium PFAS sorption by IFs. IX=Purolite PFA694AE. Water constituents: 200 mg L⁻¹ NaCl and 20 mg L⁻¹ humic acid; pH 6.4; Sorbent: 10 mg L⁻¹; PFAS: (PFOA, PFHxA, GenX, 1 μg L⁻¹ each); Equilibrium time: 21 h. Error bars: Standard deviation of 3 experiments. Some error bars are obscured by the columns.
