A) Time dependent GenX sorption by IF‐1 ([GenX]₀=1 μg L⁻¹; [IF‐1]=10 mg L⁻¹). pH 9.7. B) GenX Sorption Isotherm by IF‐1 ([IF‐1]=100 mg L⁻¹; [GenX]₀=0.2–50 mg L⁻¹). Lines show fit to Langmuir (red, solid) and Freundlich (blue, dashed) models. C) Regeneration and reuse over 5 cycles of IF‐1. IF‐1=20 mg, [GenX]=18 mg L⁻¹ (20 mL); extraction with 400 mM ammonium acetate in 1 : 1 EtOH:H₂O (20 mL). Error bars: Standard deviation of 3 experiments.
