- 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.
