Popis:	The The mobility of dioxane molecules in the calcium-forms of two samples of zeolites of the faujasite-type, as measured by NMR, is discussed in comparison to earlier results obtained for the sodium forms. Differences in mobility can be explained in terms of the number of cations in the large cages of the zeolite and of the depth of the potential holes near the cations for different Si/Al-ratios. Strong restrictions in mobility for high dioxane contents are common for all samples.
