Abstract

The activated carbon produced from agricultural waste, Tapioca Peel, was used for the adsorption of reactive dye Megenta MB from its aqueous solutions. The preparation of activated carbon from agricultural waste could increase economic return and reduce pollution. In our project, adsorption studies were performed by varying parameters such as dye concentration, pH of the dye solution and contact time. The study investigates the removal of Megenta MB dye from its aqueous solution. The equilibrium adsorption data obtained were used to calculate the Freundlich and Langmuir isotherm parameters. Higher adsorption percentages were observed at lower concentrations of Megenta MB. Optimum pH value for dye adsorption was determined as 7. Maximum dye was removed within 120 min after the beginning for every experiment.
