a–d Changes in the concentration of PFOA (a), the adsorbed amount (qt) of PFOA (b), TOF (c), and 107 PFAS (d) vs. time. e Removal efficiencies to 51 PFAS with initial concentration > 10 μg L−1. f The total concentration removal of 107 PFAS. Experiment conditions for AC and PFA694E adsorption: 100 mg AC or PFA694E, 300 mL fluorochemical wastewater. Experiment conditions for Al/Fe or Zn-based EC: 100 cm2 of Al/Fe or Zn electrode, 300 mL fluorochemical wastewater, 3 mA cm−2 of applied current density. All the error bars in this figure represent the standard deviation of the data from duplicate tests.
