  • The Preparation of Activated Carbon from Coconut

    Activated carbon has been successfully prepared from coconut shell charcoal using novel dry mechano-chemical activation with KOH and planetary ball mill. The combination of chemical activation and mechanical activation on coconut shell charcoal is found to increase its micopore volume and surface size. These increase yielded to a high adsorption capacity which was measured at 298 K and 268 KSolvent-free synthesis of magnetic biochar and ,2020-6-20 · Ball-mill extrusion magnetic biochar and activated carbon was obtained and compared. • The properties and adsorption mechanism of magnetic absorbents was explored. • Magnetic biochar had higher adsorption capacity than magnetic activated carbon. • The maximum adsorption capacity of methylene blue was 500.5 mg/g. •
