The present study involves the incorporation of uranyl ion into Y-zeolite. The Na+- UO2+2 exchange in the framework was measured by neutron activation analyses. The X-Ray diffraction patterns of the materials have been studied in order to understand the behavior of uranyl ions in the zeolite and in order to present the unknown crystal data.
The Y- zeolite framework distort in response to the cation present in the structure. Hence the position of the UO2+2 in the structure was inferred from powder X-Ray diffraction data.
