AB  - The hydriding kinetics of Zr1.02Ni0.98 alloy was examined in dependence on the number of hydriding/dehydriding cycles. The rate constants relating to three subsequent hydriding procedures of an alloy sample, at five temperatures: 423, 448, 473, 498 and 523 K, were determined. The rate constant increases, and the activation energy decreases on each repetition of the hydriding/dehydriding cycle at a given temperature. This behavior was explained by sample crushing, leading to an increase in the surface area accessible to hydrogen.

AB  - The electric conductivity of the homogeneous liquid Bi-HgI2 System was measured in the temperature range 260—540 °C for several Bi mole fractions ranging from 0.00 to 0.38. The specific conductivity-composition isotherms are indicative of the occurrence of electronic conductivity also before reaching a bismuth concentration sufficient for a complete conversion of HgI2 into Hg2I2. As the temperature rises the share of electronic conductivity in the total conductivity abruptly increases. Comparing the properties of this system with those of the BiI3-Bi System the conclusion is drawn that electronic conductivity in liquids is due to free metal atoms.

Applying a semi-empirical algorithm the complex experimental curves were resolved into elementary ones. It turned out that in zeolites with bivalent cations there are four phases of sorbed water. Sorption heats were determined for each individual phase. The NMR spectra of water on a CaA zeolite were investigated. They also point out the existence of four phases. On the basis of the results obtained a possible model of water sorption on synthetic zeolites with bivalent cations is discussed.

AB  - 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 that included
nitrate does not disturb the zeolite structure. First indications of a
change of the type A zeolite structure and of the appearance of
new phases were obtained with the inclusion complexes formed at
about 600°C, such as LiA.LiCI and LiA.LiBr[3, 4]. We assumed
the temperature to be the factor responsible for the transformation,
and therefore we tried heating inclusion complex with
included nitrate, NaA.NaNO3. The structural change and the
identification of the phases are presented in this paper, while the
properties and application of the new solid phase is a subject of

Complexon III was found to form complexes with Cd, Pb, Ni and Zn ions in the ratios 1:2 for Cd and Pb, 2:1 for Ni and 1:1 for Zn. Cadmium and lead complexes can be reduced at the DME with E1/2=-0.70 V for the cadmium complex and E1/2=-0.59 V for the lead complex (vs. a calomel reference electrode). Diffusion coefficients D=1.5×10-6 cm2 s-1 and D=2.5×10-6 cm2 s-1 were found for non-complexed cadmium and lead ions, respectively. Complexes of cadmium and lead with complexon III gave values of D=3.0×10-7 cm2 s-1 and D=3.7×10-7 cm2 s-1, respectively, at 170°C. The activation energy of the complexed and non-complexed Cd ion diffusion current Q=4.50 kcal mol-1 and the heterogenous electrode process rate constants ke0=2.5×10-6 cm s-1 for the complexed ion have been determined.

AB  - 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 and a monolayer adsorption on the zeolite NaA is suggested on the basis of linear Langmuir plots. Demethylation of methylene blue in the presence of the denitrated zeolite has been shown from the changes in the absorption spectrum of the solution. In an alcoholic medium the demethylation is partial and yields the neutral trimethylthionine, TMT. In aqueous medium the demethylation process leads to the completely demethylated product, thionine, and the reaction occurs as a secondary process on the zeolite surface. The demethylation is base catalyzed by the activity of the strongly electronegative surface of the denitrated zeolite NaANa2O. A mechanism of demethylation in aqueous and alcoholic media has been suggested.

Adsorption isotherms have a standard form and a monolayer adsorption on the zeolite NaA is suggested on the basis of linear Langmuir plots. Demethylation of methylene blue in the presence of the denitrated zeolite has been shown from the changes in the absorption spectrum of the solution. In an alcoholic medium the demethylation is partial and yields the neutral trimethylthionine, TMT. In aqueous medium the demethylation process leads to the completely demethylated product, thionine, and the reaction occurs as a secondary process on the zeolite surface. The demethylation is base catalyzed by the activity of the strongly electronegative surface of the denitrated zeolite NaANa2O. A mechanism of demethylation in aqueous and alcoholic media has been suggested.",
