Abstract
The production of activated carbon from sacha inchi seed shell for methylene blue removal was studied. The effects of KMnO4 impregnation ratios (0-5% wt./wt.) and activation temperature (250-400°C) were evaluated. It was found that the optimum activating temperature and impregnation ratio are 350°C and 1 wt.% KMnO4, respectively. The product made under these conditions is stable and suitable for adsorption in aqueous solution. Maximum methylene blue adsorption was achieved at pH 3 and with a relative decrease to about 95-96% adsorption efficiency between pH 4 and 9. The equilibrium adsorption data showed a good fit with the Freundlich isotherm exhibiting 99.80 mggG1 adsorption capacity.
