This study aimed to investigate the efficiency of the electro-persulfate process in removing acid blue 25 from aqueous solution. In order to optimize the parameters, the OFAT method was used, and the effect of three main parameters, including pH, sodium persulfate salt concentration, and current intensity was investigated. According to the results, the optimal removal efficiency of 94% in 60 minutes was obtained under conditions of pH=5, the initial concentration of sodium persulfate=250 mg / L, and the current=500 mA. According to the results of this study, the electro-persulfate process sulfate process can be an efficient process for dye removal from industrial effluents.
