Mass transfer process in the removal of Congo Red (CR) onto Natural Clay (NC): Kinetic, isotherm modeling, and thermodynamic study
Published 2023-08-01“…The adsorption isotherms at different temperatures have been used for the determination of thermodynamic parameters, i.e., the negative free energy ΔG0 (10.081 to 1.087 kJ/mol), positive enthalpy change ΔH0 Q5 (64 = 175 kJ/mol) values indicate that the overall CR adsorption is spontaneous and endothermic in nature. HIGHLIGHTS The aim of this study was to evaluate the adsorption of Congo Red onto Natural Clay (NC).; The effects of parameters were investigated graphically.; Under optimized conditions, up to 212.766 mg/g at 25 °C is removed from the solution.; The adsorption kinetics were found to follow rather a pseudo-second-order kinetic model.; The thermodynamic parameters indicate the adsorption is spontaneous and endothermic in nature…”
