The objective of this study is to assess the uptake of hexavalent chromium Cr(VI) from aqueous solutions onto Fly ash. Fly ash samples were collected from Shri Ram fertilizers and Chemicals Ltd. (SRFC) Kota, Rajasthan. The study investigates the effect of temperature. Thermodynamic parameters such as enthalpy change (ΔH˚), free energy change (ΔG˚) and entropy change (ΔS˚) were calculated. The ΔG˚ and ΔH˚ values for Cr(VI) adsorption on the fly ash showed the process to be spontaneous and endothermic in nature. The equilibrium data for the adsorption of chromium were analysed in the light of Langmuir and Freundlich isotherm models.
