Abstract EN
Adsorption of dyes from aqueous solution on the surface of granite was accomplished under the optimized conditions of temperature, initial concentration, pH, contact time and weight surface.
Spectroscopic technique was used for the measurement of dyes before and after adsorption.
The applicability of Langmuir and Freundlich adsorption isotherm equation for the present system was also tested.
Thermodynamic parameters such as change in the free energy (ΔG), the enthalpy (ΔH), the entropy (ΔS) and activation energy (Ea) were favourable, endothermic and spontaneous.
Kinetics of adsorption was studied by using Lagergreen's equation at optimum pH and the adsorption rate constant kad was calculated.
The data showed that the pseudo–first-order model was best fit model.
