Adsorption of Fe (III) Ions by Activated Calcite Powder - Equilibrium, Kinetic and Thermodynamics Studies
Journal Title: Journal of Biomedical and Pharmaceutical Research - Year 2013, Vol 2, Issue 1
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 (ΔG0), Enthalpy (ΔH0), and Entropy (ΔS0) were calculated and the result shows that the adsorption process is physical adsorption.
