In this work, the degradation of Basic Red 29 (BR29), an azo dye, was investigated using a high-frequency ultrasonic reactor (300 kHz). The influence of several parameters such as initial substrate concentration (5–200 mg L−1 ), pH (3–10.1), ultrasonic power (20–80 W), and nature of the dissolved gas (Ar, air, and N2) on the degradation of BR29 was assessed. Additionally, the impact of natural matrices (seawater and natural and river waters) on the degradation rate of BR29 was clarified. |
