Abstract

In the present study the feasibility of activated carbon prepared from Eucalyptus globules Bark to remove Methylene Blue from aqueous solutions was investigated by adsorption through batch experiment. The effect of various experimental parameters like initial concentration, contact time, adsorbent dose, pH and particle size has been studied to obtain information on treating effluents from the dye industry. Adsorption equilibrium data were fitted with Langmuir, Freundlich isotherm models and the kinetics of adsorption was found to be first order and the intra-particle diffusion as the rate determining step. The adsorption capacity of dye has been compared with Commercial Activated Carbon (CAC). The results indicate that the Eucalyptus globules Bark Carbon (EGBC) is promising material and alternate of CAC for adsorption of MB from aqueous solutions.
