The current study examines Acid Yellow 17 (AY17) degradation utilizing a dual-frequency sonochemical reactor at 4 L capacity. The effects of several factors including pH, ultrasonic power, initial concentration, and combination with oxidants (H2O2, Fenton's reagent, and persulfate) on the AY 17 decolorization has been elucidated in details. Only sonication achieved 64.4% AY17 decolorization under optimized conditions of AY17 initial concentration (25 ppm), acidic environment (pH 3), power (250 W), and dual frequency operation. Fenton reagent increased the AY17 decolorization to a maximum extent (̴100%) compared to US + H2O2and US + KPS combinations when various oxidants were applied. Kinetic investigations for several treatment approaches were also carried out. The Box–Behnken design was also used to model the US + Fenton and US + KPS processes, and the ideal parameters for efficient AY17 decolorization were elucidated. Overall, a novel combination approach has been developed for efficient decolorization of AY 17 for the first time. |
