Ion exchange in a mixture of RbNaX and NaY zeolites after different treatments was studied by lz9Xe-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 scal
