    abstract = {The production of activated carbon from sacha inchi seed shell for methylene blue removal was
studied. The effects of KMnO<sub>4</sub> impregnation ratios (0-5% wt./wt.) and activation temperature (250-400&deg;C) were
evaluated. It was found that the optimum activating temperature and impregnation ratio are 350&deg;C and 1 wt.%
KMnO<sub>4</sub>, 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.}
