Abstract

The study tested the applicability of using pelletized titanium dioxide on the photocatalytic decolorization of a solution containing Rhodamine B dye, a representative of the xanthene dyes. Six parameters namely titanium dioxide-cement ratio, initial dye concentration, pH, temperature, light source and irradiation time were considered in the parametric study. By A NOVA, four main factors including titanium dioxide-cement ratio, initial dye concentration, temperature and light source significantly affect the degradation process of the dye. While two-factor interactions like initial dye concentration and pH, temperature and light source, temperature and irradiation time and light source and irradiation time were the significant interactions. The pelletized titanium dioxide was found to be effective in the photocatalytic process. Also, the extent of color reduction due to adsorption was found to be very indicating that decolorization of the dye was mainly due to the photocatalytic process.However, the irradiation time for the photocatalytic process may still be extended up to 130 minutes to reach higher dye decolorization. Further, investigation on the use of other binder, pellet production, addition of hydrogen peroxide and reusability of pellets were also recommended.
