Background and aims: Colored wastewaters are highly toxic for animals, human and habitat areas and cause several diseases in humans such as allergy, cancer and mutation. This study was aimed to remove of acid blue 113 color with application of UV/H2O2 with nano-catalyst of Fe3O4. Optimization of the process was investigated using experiment design methodology.
Methods: In this experimental study, in order to study the effective  parameters such as initial concentration of acid blue 113 (AB 113), pH, contact time, amounts of hydrogen peroxide and nano-catalyst Fe3O4 in removal of acid blue 113 and finding optimal conditions was investigated using of response surface methodology. Data were analyzed using design experiment software.
Results: Optimum conditions of removal including initial concentration of AB113 dye 62.3 mg/L, pH 3.83, contact time 29.5 minutes, the amount of hydrogen peroxide 31.53 mmol/L and concentration of Fe3O4 1.81 g/L were obtained for maximum removal efficiency of 95.51%. The removal efficiency by increasing H2O2, contact time and catalyst concentration increased and with increasing of initial dye concentration and pH was decreased.
Conclusion: The results showed that the removal amount of AB113 dye from synthetic wastewater using UV/H2O2/Fe3O4 process obtained 95.51% in optimal condition. Therefore, this method has an effective potential in AB113 removal and can be applied for removal of this dye from industrial wastewater.
Keywords: Acid blue 113, UV/H2O2/Fe3O4 process, Iron nano catalyst, Response surface methology.
