Figure 7. Removal of (A) BPA and (B) linear transform ln(C₀/C) of kinetic curves of NGD, Fe⁰@Fe₃O₄ and the prepared FNGD composites. (C) Removal of BPA in different systems. Effect of (D) BPA concentration, (E) PMS concentration, (F) 0.6-FNGD dosage, (G) initial pH and (H) inorganic anion effect on BPA degradation in 0.6-FNGD/PMS/Vis system. (I) Fe leaching concentration of 0.6-FNGD during the degradation process. General conditions: C₀ (BPA) = 15 mg/L, C₀ (catalyst) = 0.5 g/L, C₀ (PMS) = 50 mg/L, V = 30 mL, temperature = 293 K, initial pH = 7.0.
