Synthesis of TiO2/Vulcanic Ash as Photocatalyst for Batik Wastewater Treatment in Household Scale

Abstract

The TiO2/Vulcanic ash as a photocatalyst for batik waste treatment has been conducted in this study. thas been synthesized in this study. Titanium precursor has been dispersed into volcanic ash powder suspension followed by drying and calcination. Characterization of material was conducted by using X-Ray Diffraction (XRD), X-Ray Fluorescence (XRF), Fourier Transform InfraRed (FT-IR) and spectrophotometer UV-Visible. The material was applied in batik’s waste water photooxidation at varied treatment of the addition of H2O2 and potassium peroxodisulphate as oxidant. In this research, from varied treatment is concluded that with addition of potassium peroxodisulphate have better effectivity than using H2O2. TiO2/Vulcanic Ash is a potential material that can be developed for batik’s wastewater treatment under photooxidation mechanism with low-cost treatment and friendly for environmental.
