Description:

(abstract)

133Cs magic angle spinning nuclear magnetic resonance (MAS NMR) spectroscopy revealed two Cs sites in Csadsorbed aluminium altered phlogopite (Cs Al-Phl), but only one site for Cs-adsorbed magnesium altered phlogopite (Cs Mg-Phl). Cesium ions in hydroxyl interlayered vermiculitelike
layered silicate reside at sites in both mica zones and in interlayer wedge zones of Al-Phl. It is likely that chemical exchange of Cs+ ions occurs between these two zones.
