摘要：

Ion exchange in a mixture of RbNaX and NaY zeolites after different treatments was studied by 129Xe-NMR of adsorbed xenon. The presence of water greatly favours the ion-exchange process. But this latter can also occur under water-free conditions upon heating. The exchange rate (on the NMR time scale) of adsorbed xenon between different zeolite crystallites depends on the experiment temperature. © 1990.
