Özet: In this study, color and chemical oxygen demand (COD) removal of Acid blue 264 azo dye by Fenton and ultrasound-Fenton methods was investigated. For this purpose, the effects of parameters such as initial pH, H2O2 concentration, Fe2+ concentration and reaction time were studied comparatively. The highest color and COD removal for Fenton process found at the optimum condition of pH = 3.5, [Fe2+] = 180 mg / L, [H2O2] = 125 mg/L and reaction time 75 minutes were 88.5% and 76%, respectively. In the Ultrases-Fenton process, at 20 kHz ultrasound frequency, when pH = 3,5, [Fe2+] = 180 mg/L, [H2O2] = 100 mg/L and reaction time was 45 minutes, the highest color and COD removal was achieved as 96.6% and 88.5%, respectively. The results showed that the color and COD removal increased with reduced chemical consumption in the ultrasound-Fenton process. In addition, the reaction time is shortened compared to the Fenton process. According to the data obtained, the ultrasound Fenton process can be used as an alternative method for the removal of Acid Blue 264 azo dye more economically than Fenton method with its shorter reaction time and less chemical consumption.
