Abstract
The localization of Na+ and Ag+ ions in hydrated zeolites NaAg-Y containing 2, 7.25 and 14 Ag+ ions/u.c. is studied by X-ray diffraction. A high preference of Ag for site I is observed. On increasing the silver content the Ag occupancy of site I reaches a maximum value of ~4 Ag/u.c. at the expense of Na+ ions in site I'. The Ag to Na preference pattern derived is; site I > site II > site 1' ~ unlocalized.
