ABSTRACT:

The present work investigates the equilibrium adsorption of Chrysene on multi-walled carbon nanotubes at 293, 303 and 313°K, and determines the equilibrium adsorption isotherms and thermodynamic parameters (ΔG, ΔH and ΔS). The values of ΔH and ΔG suggested that the adsorption of Chrysene onto MWCNTs was endothermic and nonspontaneous.The experimental data were analyzed using Langmuir, Freundlich and Temkin isotherm equations. The experimental results showed that a well conformity between experimental data and isotherm models.
