Adsorption of Methyl Orange from Solution by IOCZ in Batch Mode: Equilibrium Study

Article Preview

Abstract:

The research was designed to test the properties of Iron-Oxide-Coated-Zeolite (IOCZ) for adsorption of methyl orange (MO) from synthetic solutions. Contact time and equilibrium MO concentration were adopted to study their effects on MO adsorption. The results showed that adsorbent quantity of MO onto IOCZ increased with the equilibrium concentration increasing. The equilibrium data was fitted better by Freundlich model. The thermodynamic parameters (ΔG0, ΔH0, and ΔS0) were also determined from the temperature dependence. The results showed that the process of adsorption MO was spontaneous and endothermic process and an increase in temperature favored the adsorption.
