a, b The SMX removal efficiencies and the corresponding reaction rate constant in Fe-Nx SACs/PMS (Inset: the fitting plot). c The kvalue of different catalysts in various PMS-based Fenton-like systems. d The oxidation activity of Fe-N4 and Fe-N2 SACs in the existence of various pollutants. e The removal rate of SMX within 1 and 4 min in Fe-N2 SACs/PMS systems with various anions and NOM. f SMX removal efficiencies in the presence of different actual wastewater in Fe-N2 SACs/PMS. [organic]0 = 10 ppm, [catalysts]0 = 0.1 g L−1, [PMS]0 = 1.0 mM, [Cl−]0 = [SO42−]0 = 20 mM, [HCO3−]0 = 10 mM, [CO32−]0 = 5 mM, [HA]0 = 5 ppm, pH0 = 6.3, pHover = 5.8. The error bars in the figures represent the standard deviations from triplicate tests.
