17O MQMAS NMR studies of Na-A and Ca-A.
We report, for the first time, 17O MQMAS and 17O/23Na double resonance NMR studies on calcium-exchanged zeolite sodium-A; the results show that the isotropic shifts of the framework sites are strongly affected by factors including the hydration level and nature of the charge-balancing cations.
