Abstract Activated carbon preparation from sugarcane leaves and rice straw by carbonization (250°C–400°C) and activation at 500°C were studied. The effects of pre-oxidation, hydrolysis of derived charcoals by boiled KMnO4 aqueous solution were evaluated. The derived charcoals products were pretreated using oxidation-hydrolysis with 1–5 wt.% KMnO4 at 100°C and then activated at 500°C. The derived charcoal and activated carbon products were characterized by FTIR, XRD, SEM-EDS and BET. Iodine number and methylene blue number of derived products were also used for the analysis of the products. It was found that fabricated charcoal materials made at 350°C–400°C possess… More >
