dc.description.abstractAdsorption of Deep Red (DR) on activated carbon (AC) produced from chestnut shell has been studied. Chemical activation process with ZnCl2 was applied to the ground chestnut shells at 3:1 (ZnCl2/Raw Material) impregnation ratio, and then at 500 °C, the carbonization process was used to produce AC. The surface area of the AC was defined as 2187 m2/g. Effects of AC dose, contact time, pH, temperature and initial concentration on deepred adsorption have been studied. In experimental studies, 97.4% dye removal was achieved using 0.1 g AC at pH 2.5, 45°C and at 100 mg/L. Dye removal has been seen to increase at all initial concentrations as the temperature increased. The kinetic data are corresponding to the pseudo 2nd order kinetic model. The finding was that the adsorption process corresponding to the Freundlich isotherm model. According to ΔS, ΔH, and ΔG thermodynamic data, DR adsorption on AC is an endothermic and chemical adsorption. The study’s findings revealed that AC prepared from chestnut shell is suitable for removing DR from aqueous solutions.
