Thermodynamics of Cr(VI) Adsorption on Thiourea Chelating Ion Exchange Fiber

Article Preview

Abstract:

A chelating ion exchange fiber containing thioureido groups for the removal of Cr (VI) has been prepared from chloramethylated styrene grafted polypropylene fiber (2.96 mmol/g Cl) reacted with thiourea, batch adsorption experiments are adopted to investigate its adsorption equilibrium properties, Adsorption isotherms at various temperatures were obtained. Langmuir linear equation model can well describe the adsorption equilibrium data suggesting that the adsorption process involves both chemisorption and physisorption. The values of thermodynamic parameters, including ΔH, ΔG and ΔS, indicate that the adsorption of Cr (VI) is a spontaneous, entropy-driven and endothermic process.
