Indonesian Modified Clay for Dye Waste Treatment

Abstrak

Synthesis and Characterization of TiO₂ Coated on Clay Pillared Alumina (PILC) for Methyl Orange Photodegradation Under UV Illumination. The synthesis included both pillarization the clay with alumina and TiO₂ coated on PILC using impregnation method. Some characterizations also were employed to this research such as X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), N₂ Adsorption Isotherm and UV-Visible Diffuse Reflectance (DR UV). The photocatalyst was then used to decompose waste dye, methyl orange (MO). Among three photocatalysts that were successfully synthesized, PILC Ti 1.0% had the highest activity to decompose the waste dye.
