Activated carbons were prepared from phragmites australis by chemical activation with KCO (1:1w)(AC1), ZnCl(1:1w)(AC2), NaOH (1:1w)(AC3), and 28.5% HPO (AC4) followed by pyrolysis at 800C in steam atmosphere. Different activated carbons have been used for the removal of methylene blue (MB) dye from aqueous solutions. The optimum condition for the production of colorless methylene blue aqueous was determined. The activated carbon prepared by chemical activation with KCO attained a maximum value of 153 (mg/g) at a carbonization temperature of 800C with activation duration of 30 min and at an impregnation ratio of 1.0. Porosities of activated carbons were characterized by cyclic voltametry and electrochemical impedance spectroscopic and SEM techniques.
