Figure 7
Pseudo-first-order plot for determination of the apparent CIP degradation rate in a photo-assisted Fenton-like process in the presence of (A) various loadings of the catalyst, and (B) with the use of different initial concentrations of H2O2. Reaction conditions: catalyst (Cu3(PO4)2, 25 mg, or other if indicated), H2O2 (50 μL, 30%, or other if indicated), CIP (100 mL, 15 mg/L), room temperature, stirring rate (600 rpm), visible light (λ ≥ 400 nm), without pH adjustment (native pH ~ 6.5).
