The kinetics of sorption of basic dyes, (methyl blue and basic blue 3) from aqueous solution by charcoal activated at 1000oC, prepared from the wood of Bombax cieba was investigated. It was found that the adsorption process follow first order kinetics. The rate constant (k) increased with the rise in temperature showing endothermic nature of the adsorption process. Activation energies for methylene blue basic blua 3, were found to be 2.33 and 8.74 kj/mol respectively.
