Abstract
This study was undertaken to carbonize pericarp of peanut, an agricultural waste material, in the presence of various concentrations of pure sulphuric acid at different activation temperatures. Percent yield of the product was determined and its adsorption capacity was measured against methylene blue. The best adsorption capacity was obtained at 700°C with 9N sulphuric acid in solid-liquid ratio of 1:4. Increase in combustion loss as well as activity was also observed with rise in temperature. Key words: activating agent, active carbon production, adsorption capacity, peanut pericarp
