Аннотация: Reprocessing of cadmium-containing wastes and used storage batteries produces cadmium oxide. Electrowinning of the metal from an alkali melt is proposed for processing of CdO and production of metallic cadmium or cadmium-sodium alloys. The design of a laboratory electrolyzer is discussed. Technological parameters of the electrolysis process are determined. Applied and engineering aspects of the electrowinning of cadmium and cadmium-sodium alloys are considered. Conditions of the electrolytic production of cadmium are optimized. Specific features of the electrochemical production of cadmium-sodium alloys are analyzed. Electrowinning of cadmium from an acid or chloride solution is considered. The comparison of the electrolysis of aqueous and alkali melts is in favor of the latter

    Novel composite solid state electrolytes on the base of BaCeO3 and CeO2 for intermediate temperature electrochemical devices / D. Medvedev, V. Maragou, E. Pikalova, A. Demin, P.

Аннотация: In the present work, nano-sized powders of (1 − x)Ce0.8Sm0.2O2−δ–xBaCe0.8Sm0.2O3−δ (x = 0, 0.3, 0.5, 0.7 and 1) were obtained by solution combustion synthesis (self-combustion synthesis, SCS) method of nitrate and various types of organic fuels (glycine, glycerin, citric acid and a mixture of citric acid and ethylene glycol). The research results indicate that the finest powders by using the SCS process are formed when the perovskite concentration is decreased in the system under study, as well as when as the fuel glycerin or a mixture of citric acid and ethylene glycol are used. The use of the specific method allows the preparation of dense composite ceramics at 1500 °C. The investigation of the electrical properties of the composites at a wide range of temperatures and oxygen partial pressures shows that 0.5Ce0.8Sm0.2O2−δ–0.5BaCe0.8Sm0.2O3−δ material is characterized by relatively good stability against CO2, acceptable value of total conductivity and the lowest contribution of electron conductivity in both oxidizing and reducing atmospheres.

Аннотация: We propose a simple and effective method to determine the carbonate impurity content in the solid electrolytes. The technique is based on the measurement of the carbon dioxide volume produced from the interaction of the investigated material with acid. Determined in this way, the content of Li2CO3 in the synthesized electrolytes Li7La3Zr2O12, Li8La3Zr2O12.5 and Li9La3Zr2O13 are 1.32 ± 0.04, 1.95 ± 0.06 and 3.49 ± 0.10 wt.%, respectively. From the obtained data, the actual lithium content per formula unit of complex oxide was calculated for the synthesized compounds. The composition with x = 9 had the highest total conductivity, σ = 7.5 × 10−6 S cm−1, at room temperature. All the investigated electrolytes have an activation energy of approximately 50 kJ mol−1.

Аннотация: The oxidative desulfurization of a straight-run, nonhydrotreated diesel fraction (boiling range 178–342°C) containing benzothiophene, dibenzothiophene, their alkyl-substituted derivatives, and thioxanthene by the action of hydrogen peroxide in the presence of transition metal compounds (Na2MoO4, Na2WO4, NaVO3, WO3, tungstic acid, and heteropoly tungstate/molybdate H3PMo6W6O40) in a biphasic system followed by the extraction of the oxidation products with dimethylformamide has been studied. The oxidation of the hydrocarbon fraction in the presence of heteropoly tungstate/molybdate under biphasic conditions provides for the removal of up to 82% of total sulfur.
