This study is part of the framework for the enhancement of agro-food waste ( olive grains) for the adsorption of a cationic dye by two methods, the first is to use its waste in a natural form (biosorbent) and the second is to the preparation and characterization chemically of an activated carbon from grain by using an activating agent (nitric acid), we studied the influence of several parameters (concentration of methylene blue, mass of olive grains, pH and temperature). The kinetic data was modeled by pseudo first order equations, pseudo-second order and intraparticle diffusion model; The Langmuir-Freundlich model was chosen for the representation of the experimental results. The experimental results are shown that the effect of the mass of adsorbent on the adsorption capacity increased respectively with increasing the mass of adsorbent and dye adsorption is promoted in a room temperature. Modeling results showed that the adsorption of methylene blue on olive grain follows the second order pseudo model for all concentrations in both adsorption and bio-sorption. The study of the isotherm shows that the Langmuir model well describes the process of adsorption of methylene blue on olive grains. All these results show that olive grains could use effectively as a low-cost adsorbent for the removal of cationic dye of an aqueous solution.
