Daftar Isi:
- Indigosol blue is one of the dyes that has not been widely studied for photodegradation. This study aims to determine the photodegradation activity of indigosol blue using TiO2/Natural zeolite. TiO2 embedded in natural zeolite was synthesized using the sol-gel method. The synthesis results were characterized using X-Ray Diffraction (XRD), X-Ray Fluorescence (XRF), and UV-Vis Diffuse Reflectance Spectroscopy (DRS). The characterization of TiO2-zeolite obtained a bandgap energy of 2.62 eV that could be seen in the UV-Vis DRS spectra. UV light is used during the photodegradation process to irradiate TiO2-zeolite photocatalyst. The results show that the optimum mass of natural TiO2-zeolite photocatalyst was 0.02 g with a degradation percentage of 58.3%. The optimum radiation time was 30 min with a degradation percentage of 58.7%, and the optimum concentration of blue indigosol was 600 ppm with a degradation percentage of 58.7%. TiO2/Natural zeolite photocatalyst could degrade indigosol blue dye effectively at the optimum condition.
