The present work aims at finding out the effectiveness of color removal using arecanut peels as an activated carbon. Commercial activated carbon is costly and uneconomical. This has necessitated the development of cheaper carbonaceous materials. Although various materials are used in the production of activated carbons abundant availability and low cost of agricultural by-products make them good source of raw materials for activated carbon. The arecanut peels activated carbon was prepared in the laboratory by carbonization followed by activation. The batch adsorption studies were carried on the simulated samples prepared using malachite green dye in the laboratory under varied conditions like contact time, pH, dosage of adsorbent and various concentrations of adsorbate. Form the batch study, it was found that the arecanut peels activated carbon dosage of 0.5g/l is optimum as it removes 91.8% of the dye at pH 10 for a contact time of 35 minutes for dye concentration of 5mg/l.The sorption data follow Langmuir model as well as Freundlich model. Results in this study indicated that powdered arecanut peels activated carbons was an attractive candidate for removing dyes from dye wastewater.
