    Abstract

    Most of the textile industries today used the synthetic dyes which recalcitrant in nature and contain the dangerous poisonous material property. However, the application of the synthetic color can be harmful to the environment because the colored wastewater produced from their processes is difficult to degrade. The application of Advanced Oxidation Processes (AOPs) for dye wastewater treatment is the focus of this study. Photocatalysis as one of the AOPs was applied for the decolorization of the organic content of synthetic dye wastewater. The reactive dye, C.I. Reactive Red 2 (RR2) was used as the model organic pollutants. In this research, the bulk and nanoparticle of titanium dioxide (TiO2) catalyst were immobilized on a plastic surface. The solar-induced photocatalytic decolorization process was performed in a 220 mL of cylinder glass reactor. The catalyst concentration was varied from 0 to 0.4 g/mL. The RR2 concentration was varied between 25-100 mg/L. Degradation of organic content in the pollutant was examined in the term of color removal within 0-15 hrs under solar irradiation. By using a dye concentration of 25 mg/L and the catalyst concentration of 0.4 g/mL, a color degradation of 95% and 46% was achieved when using nano and bulk TiO2 respectively, after irradiation for 15hours. A pH of 6-7 was observed during the process.
