Abstract

Background & Objectives: The Azo dyes due to presence of aromatic rings in structure are considered major problems into the environment. In this experimental study, the synergistic effect of persulfate and nano zero-valent iron in degradation of Acid Blue 113 in presence of ultrasonic irradiation was investigated.Materials and Methods: The effect of operating parameter such as initial pH, different concentration of S2O8 2-, nZVI and initial dye using a batch ultrasound reactor at 40 kHz frequency was investigated. After the optimize process, synergistic dye degradation and COD reduction of colored solution was studied. For characterization of the prepared nZVI particle, transmission electron microscope (TEM) image was used.Results: To remove 99% dye with initial concentration of 50 mg/L, the optimal condition in the end of 30 min of reaction was pH 3, concentration of S2O8 2- and nZVI 5 mM and 50 mg/L, respectively. In the same of condition with increasing pH to 11 the dye removal efficiency decreased to 17%, respectively. After 120 min of reaction in the optimal condition, the COD reduction was 95%. Synergistic dye degradation in US/S2O8 2-/Fe0 process was observed 59%. The TEM image of the synthesized nZVI confirmed the nanoscale Creation.Conclusion: The US/S2O8 2-/Fe0 combined process due to high synergistic degradation, CAN BE PROMISING PROCESS TO INDUSTRIAL WASTEWATER TREATMENT.
