Abstract :
Background: Reactive dyes, anionic compounds with high water solubility, are widely used in textile industries.
Objectives: The present study aimed to assess the feasibility of the photo-Fenton process in removing Reactive Red 198 dye from aqueous solutions and determine the optimal conditions for maximum removal.
Materials and Methods: This study was performed on a laboratory scale using a 4-liter photochemical reactor. The spectrophotometer DR5000 (wavelength 520 nm) was used to determine the dye concentration. The effect of the influencing parameters, including pH (3–9), Fe (II) concentration (10–200 mg/L), H2O2 concentration (25 - 150 mg/L), initial dye concentration (50–200 mg/L), and reaction time (15 - 120 minutes) were studied.
Results: According to the results, the photo-Fenton (UV/ H2O2/Fe (II)) process significantly removed dye from the aqueous solution. The Reactive Red 198 dye removal efficiency from aqueous solutions was more than 99% at optimal conditions (pH = 3, Fe (II) = 10 mg/L, H2O2 = 75 mg/L, initial dye concentration = 50 mg/L, and reaction time = 120 minutes).
Conclusions: The present study demonstrated that the UV/ H2O2/Fe (II) process could be used as an efficient, reliable method for removing Reactive Red 198 dye from textile wastewater.
