Abstract
Investigational studies were carried out to adsorb toxic brilliant green dye from aqueous medium using palm fronds activated carbon. The effects of initial dye concentration, contact time were studied for the adsorption of brilliant green in batch mode. The adsorption kinetic has been described by first-order, pseudo-second-order, Elovich’s and intra-particle diffusion models. It was observed that the rate of dye adsorption follows pseudo-first-order model for the studied dye concentration range. The adsorption reached equilibrium after 150 minutes of contact. Adsorption isotherms were also used to fit the experimental data. It was found that the adsorption of brilliant green on palm frond activated carbon follows the Langmuir and Temkin adsorption isotherm models. The maximum adsorption capacity was found to be 45.45 mg.g-1.
