(A) Pseudo-first-order plot for the determination of the apparent CIP degradation rate in a photo-assisted Fenton-like process in the presence of 2-propanol as the hydroxyl radical scavenger. (B) Efficiency of CIP degradation during five subsequent reaction cycles. Reaction conditions: catalyst (Cu3(PO4)2, 50 mg), H2O2 (100 μL, 30%), CIP (100 mL, 15 mg/L), room temperature, stirring rate (600 rpm), visible light (λ ≥ 400 nm), without pH adjustment (native pH ~ 6.5).
