Wastewater treatment has used efficient technology methods that can remove any pollutant. Advanced oxidation is one of the alternative methods to reduce wastewater loads from any water pollution source. The present study was conducted to evaluate the possibility of applying photo-Fenton (UV/Fe+2/H2O2) compared to photo-Fenton-like (UV/Fe+3/H2O2) using Fe+2 or Fe+3 as a catalyst for removing Direct Orange 118 (DO 118) dye from wastewater. The experiments were conducted in a batch system under different parameters, such as irradiation time, pH, H2O2 concentration, concentration of Fe+2 or Fe+3, temperature, and the dye’s initial concentration. The highest decolorization of DO 118 was 97.817% and 91.244% for photo-Fenton and photo-Fenton-like processes, respectively, at optimum conditions of pH 3, temperature= 30 °C, and dye concentration= 10 mg/l within irradiation time= 105 min. On the other hand, for the photo-Fenton process, Fe+2 concentration was 50 mg/l, H2O2 concentration was 400 mg/l, and for the photo-Fenton-like process, Fe+3 concentration was 80 mg/l, and H2O2 concentration was 600 mg/l. The discoloration kinetics study followed pseudo-first-order kinetics for photo-Fenton and photo-Fenton-like processes. The present study results indicated that the photo-Fenton and photo-Fenton-like processes can be utilized for treating DO 118 dye from wastewater.
