Abstract: Activated carbon adsorbent prepared from Brachychiton Populneus fruit shell, biomass materials, is used for the removal of Methyl Green (MG) from aqueous solutions. For the purposes of the experiment (characterization of the adsorbent), we have used various methods, namely BET, FTIR and SEM. The various parameters influencing adsorption: contact time, initial concentration, mass of the adsorbent and temperature have been studied in batch systems. The modeling of the experimental data showed that the pseudo-second order model perfectly described the adsorption kinetics and the Langmuir model seems to be the most suitable for the equilibrium data with a maximum adsorption capacity of 67.93 mg/g. The thermodynamic study revealed that the adsorption of the MG dye is a spontaneous and exothermic phenomenon. This study confirms that activated carbon prepared from agricultural wastes has a high adsorption potential, making it an effective means for removing MG from aqueous solutions.
