The adsorption of eosin by peanut hull, which was esterized by methanol was studied with variation in the parameters of contact time, pH, initial eosin concentration and temperature. They were used to determine the optimal experimental conditions. The adsorption equilibrium was well described by the Freundlich model, although they could be modeled by the Langmuir model as well. The adsorption followed the pseudo-second order model. The mass transfer model as intraparticle diffusion was applied to the experimental data to examine the mechanisms of the rate controlling step. It was found that the intraparticle diffusion is becoming the significant controlling step under the experimental conditions. The thermodynamic constants of the adsorption process were also evaluated. The results in this study indicated that methanol esterized peanut hull was a good adsorbent for removing eosin from aqueous water.
