Solid-state ion exchange dynamics of cadmium in zeolite Y

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

The ion exchange between zeolite Na-Y or NH4-Y and CdCl2 salt was studied in the solid state between 25 and 500 °C. The in-situ high-temperature X-ray powder diffraction (HT-XRPD) technique was used in high vacuum. Only the NH4-form was active in the ion-exchange process. The exchange was found to proceed also in absence of physically adsorbed water. The results substantiated that the exchange kinetics was governed by the transport rate of the CdCl2 in the micropores.
