An activated carbon with a high surface area and outstanding adsorption properties was prepared for dye removal from water. The new adsorbent was obtained from the chem. activation and pyrolysis of sodium CM-cellulose (CMC). This activated carbon was employed to analyze and characterize the adsorption mechanism of three dye mols.: methyl violet, allura red and congo red. Different characterization techniques and exptl. adsorption isotherms quantified at different temperatures (25-45°C) were utilized to interpret the dye adsorption mechanism. A double layer adsorption model was employed to estimate the steric and energetic parameters associated with the adsorption of these dye mols. The modeling results provided the possible adsorption orientations of these dyes on adsorbent surfaces at different operating temperatures and the number of bonded dye mols. per functional group of this adsorbent was also analyzed. Calculated adsorption energies showed that both exothermic and endothermic processes were feasible for these dyes and phys. forces were involved in the adsorption mechanism. Overall, this new adsorbent showed a competitive performance for dye removal in aqueous solution and can be a potential option for industrial applications.
