Abstract

Casuarina equisetifolia empty fruit has been utilized as activated carbon material because it is abundantly available in nature. The fruit was activated by metals hydroxide, namely potassium hydroxide and sodium hydroxide for dyes adsorption. The present work was aimed to evaluate the adsorption properties of activated carbons towards cationic dye (methylene blue) and anionic dye (congo red). Results show that KOH activation yields activated carbon with excellent maximum adsorption capacities of 614 mg/g and 340 mg/g for methylene blue and congo red, respectively. The adsorption data were analysed using isotherm and kinetic models and displayed a good regression with Langmuir and pseudo-second-order kinetic models.
