A Study on the Interaction of FeCl3 with Montmorillonite Suspensions

Calorimetric and static techniques were employed to study the interaction of FeCl3 with sodium montmorillonite in dilute aqueous suspension. The results show that the amount adsorbed and the adsorption enthalpy are strong functions of the pH and temperature. The adsorption mechanism was discussed on the basis of the experimental data.
