Enhancement of TiO2 behavior on photocatalytic oxidation of MO dye using TiO2/AC under visible irradiation and sunlight radiation

► Usage of TiO2/AC for the treatment of the wastewater containing dyes and pigments. ► Adjusting experimental conditions for MO removal using TiO2/AC. ► Usage of solar energy as well as visible light in MO degradation. ► Reuse of TiO2/activated carbon after dye removal. ► Reuse of wastewater containing azo dyes in agriculture purposes.
