dc.description.abstractThis study evaluated the equilibrium, kinetics, and thermodynamics of vanadium sorption from aqueous solution onto nanocomposite functionalized with diethylene triamine in batch conditions. The effects of temperature, solution pH, and initial concentration of vanadium were examined. The maximum sorption capacity of vanadium on the tested sorbent was achieved at pH 6. The sorption capacity increased with increasing temperature and initial concentration. The equilibrium adsorption data were analyzed using Langmuir, Freundlich, Temkin, Jovanovic, Toth, Sips, Khan, and RedlichPeterson isotherm models. The kinetics data were studied using pseudo-first-order, pseudo-secondorder, the fractional power, Elovich, and Avrami models. A non-linear fitting method was used to compare the best fitting of the equilibrium and kinetic data. The sorption equilibrium data were best represented by the Langmuir, Khan, Toth, and Redlich–Peterson isotherms. The adsorption kinetics was estimated to follow the pseudo-second-order kinetic model. The mechanism of vanadium sorption was analyzed with intra-particle, Bangham, Boyd, and liquid film diffusion models. It was observed that the sorption process was controlled by the film-diffusion as well as the pore-diffusion. Thermodynamic parameters (change of standard enthalpy (ΔH°), standard entropy (ΔS°), and standard free energy (ΔG°)) suggested that the sorption of vanadium onto functionalized nanocomposite was a spontaneous and endothermic process.sr
