Structural change in the zeolite inclusion complex through high temperature treatment. Denitrated zeolite
(Elsevier, 1976)
In the sodium nitrate melt, sodium zeolite, NaA, forms the
inclusion complex NaA.NaNO3[1,2] which contains sodium
nitrate molecules in the central a cage. Our earlier
investigations [3] of inclusion complexes have shown ...
An analysis of elementary processes of water desorption from zeolites of type a Part II. Zeolites with bivalent counterions
(Elsevier, 1976)
DSC and EGA were used to follow the process of water desorption from synthetic MgA, ZnA and CdA zeolites. Applying a semi-empirical algorithm the complex experimental curves were resolved into elementary ones. It turned ...
An apparatus for simultaneous determination of electrical conductivity and thermogravimetric curves of solid systems
(Springer, 1975)
A new apparatus for measurement of electrical conductivity during thermogravimetric analysis is described. Results of an investigation of the water-zeolite system in the interval -200° up to +450° prove the suitability of ...
Investigation of occluded and nonoccluded synthetic zeolites. Base-catalyzed demethylation of tetramethylthionine-methylene blue on a denitrated zeolite
(Elsevier, 1972)
The adsorption of methylene blue from aqueous and non-aqueous media onto the zeolite NaA, the occluded zeolite NaANaNO3 and the denitrated zeolite NaANa2O has been investigated. Adsorption isotherms have a standard form ...
