Abstract

The present work investigates the action of Fe (III) ions on Activated calcite powder. The influence of contact time, initial concentration, adsorbent dosage and solution pH has been done and reported. The equilibrium data were analyzed using Langmuir and Freundlich isotherm model. The pseudo – second –order, Elovich model and intra – particle diffusion were used to test the adsorption behavior, kinetic data’s. Thermodynamic free energy (∆G0), Enthalpy (∆H0), and Entropy (∆S0) were calculated and the result shows that the adsorption process is physical adsorption.

 

KEYWORDS: Adsorption isotherm, Activated Calcite Powder (ACP), Iron Solution [Fe (III)], Kinetics, Thermodynamics.
