Production of cost-effective activated carbon from tea waste for tannery waste water treatment

Abstract In this study, we attempted to develop a cost-effective activated carbon (AC) from local tea waste. AC was synthesized via pyrolysis process and used it treat tannery waste-water. A methylene blue adsorption test then conducted determine the highest capability of AC. The crystal structure microstructure were examined by X-ray diffraction (XRD) scanning electron microscopy (SEM). An average crystallite size 15 nm measured XRD while sub-nano meter scale particle confirmed SEM images. Produced for treatment industrial waste-water that results in reduction about 89–97% chromium water. addition, other physical parameters (Biochemical oxygen demand chemical turbidity, conductivity, Cr content) also significantly reduced These suggest use as well domestic
