Abstract

Ion-exchange of transition metal ions into montmorillonite was investigated using two different ion-exchange procedures. Performing ion-exchange from aqueous solution of the respective metal ion leads to material possessing measurable Brønsted acidity, while the solid-state exchange materials show predominantly Lewis acidity. Measurements by means of a derivatograph allowed us to construct a feasible reaction mechanism for solid-state ion exchange. Satisfactory correlation was found between the results calculated from the reaction steps assumed and the measurements by means of a derivatograph.
