Mechanochemical modification of low-dispersed SnO2 and high-dispersed SnO(OH)2 powders with specific surface area 6 198 m2 g−1 have been studied. The crystal, porous, electronic structure obtained products, as well their photocatalytic activity under visible light in the process dyes degradation has investigated. It established that powder is porous poorly crystalline. Its decreases after milling. On contrary, almost nonporous crystallized. increases but degree crystallinity reduces a result...
Wet gel and dried xerogel of precipitated tin oxy-hydroxide were subjected to mechanochemical microwave treatments (MChT MWT, respectively). The prepared samples studied using DTA-TG, XRD, FTIR, nitrogen adsorption–desorption. MChT MWT cause improvement crystal structure, removal structural OH-groups increase mesopores diameter as well form the meso-macroporous structure. As a result, drastic uranyl-ions sorption for all modified is observed. Sorption centers can be divided into three...
Clay minerals are widely used to treat groundwater and surface water containing radionuclides. In our study, the method of mechanochemical activation for increasing sorption capacity natural clay mineral montmorillonite was used. By adjusting grinding time, parameters mechanochemically activated were determined. X-ray diffraction method, scanning electron microscopy, determination specific by low-temperature adsorption–desorption nitrogen characterize mechanochemical-activated...
The samples of precipitated tin (IV) phosphate, modified using hydrothermal, microwave, and mechanochemical procedures, were studied in the process Cs(I), Sr(II), U(VI) ion sorption. initial investigated before after sorption XRD, XRF, FTIR, nitrogen adsorption-desorption. It was found that modification procedures transformed micro-mesoporous structure sample into a meso-macroporous structure. As result, capacity relation to all ions increases several times. This indicates determining role...
We studied mechanochemical modification of low-dispersed SnO 2 and high-dispersed SnO(OH) powders with specific surface area 6 198 m /g. They are perspective materials for photocatalysis adsorption. The aims work were: the study crystal, porous, electronic structure obtained products, evaluation their photocatalytic activity under visible light in process dyes degradation. treatment carried out air water at 300-850 rpm using a planetary ball mill Pulverisette-7 (German, «Fritsch»). used XRD...
There are many methods for synthesis of tin dioxide SnO 2 , namely sol-gel, precipitation. However, these do not allow to regulate the physical-chemical properties in wide limits stage. The most commonly obtained samples predominantly microporous as a rule. On other hand, meso-macroporous structure is required effective use sorption processes. mechanochemical and microwave treatments can be used eliminating mentioned above disadvantages. Therefore, purpose this work was study influence on...
A search for a sorbent capable of simultaneously extracting both phosphate anions and ammonium cations from highly competitive medium like the biological environment human's body was realized.For this purpose comparative study sorption ions aquatic environments in absence any backgrounds electrolytes Ringer's solution by activated charcoal, its oxidized forms mineral amorphous sorbents -powdered titanium silicate, as well spherically granular hydrous zirconium silicate dioxide, obtained...
