Effect of different oxidation parameters on PCT oxidation: (a) Effect of solution pH (PCT 10 mg/L, H₂O₂ 400 ppm, catalyst 20 mg/L) and the (b) Point of Zero charge of RTG-MIL-100(Fe); (c) Effect of RTG-MIL-100(Fe) catalyst dose (PCT 10 mg/L, H₂O₂ 400 ppm, pH 5.5); (d) Effect of H₂O₂ dosage (PCT 10 mg/L, catalyst 20 mg/L, pH 5.5) and (e) Effect of initial PCT concentration in the Fenton system (pH 5.5, catalyst 20 mg/L, H₂O₂ 400 ppm).
