Fenton Process Coupled to Ultrasound and UV Light Irradiation for the Oxidation of a Model Pollutant

Figure 1

Degradation of 4 × 10⁻⁵ mol L⁻¹ AG50 by the Fenton process using 2.85 × 10⁻³ mol L⁻¹ H₂O₂ with different iron content (mg/g Fe₂O₃) in 100 mg L⁻¹ of catalyst calcined at 500°C (at pH = 2). (●) 0.0, (■) 14.4, (▲) 18.1, (◆) 37.4, and (□) 0.0 without H₂O₂.
