Fig. 6. The effect of Fe3O4 loading (a), H2O2 concentration (b), different initial pH values (c) and light intensity (d) on the degradation of AMX. Reaction conditions: [AMX] = 30 mg L−1 (for a–d), UV irradiation: 200 W (for a, b and c), [H2O2] = 24 mM (for a, c and d), [TiO2/15 wt% Fe3O4] = 0.4 g L−1 (for b, c and d), and pH = 2.84 (for a, b and d).
