Water in Montmorillonites

Abstract:

Positron lifetime was measured for pure and water filled montmorillonites (MMT) at room temperature. The size of free volume was correlated with interlayer distances from X-ray diffraction for different content of water in MMT. Free volume in samples with water content above 10 % (mass percentage) is smaller in comparison with bulk water. Time dependence of release of water from MMT under vacuum will be discussed.
