Composite adsorbents based on a natural biopolymer matrix of chitosan, to which 4-amino-N′-hydroxy-1,2,5-oxadiazole-3-carboximidamide and its Se derivative were attached, synthesized. A complex physicochemical analysis methods indicates that the direct introduction with high ionic permeability into reaction mixture contributes formation homogeneous particles composite developed surface morphology, enhances kinetic capacitive parameters uranium sorption in liquid media. It has been...
Influence of Fe : Au ratio on the dynamics secondary electrons with varying configuration 3 O 4 –SiO 2 –Au nanoparticles for cancer X-ray therapy was investigated.
The work provides the results of one-step formation boron-containing coatings on an Mg–Mn–Ce alloy by plasma electrolytic oxidation. studies composition, structure and morphology heteroxide are presented. It was established that boron is contained in coating mainly form B or B2O3. introduction changes color coatings, also helps to increase their porosity. method determining full cross section interaction thermal neutron absorption efficiency samples material using installation...
A determination option for 238U in solutions by the neutron activation analysis was investigated. radionuclide treatment based on 252Cf used as a source. The limit of uranium using thermal neutrons 0.1 mgL?1 determined within research framework. With help preliminary concentration sample via evaporation method, it is possible to further reduce detection 2-5 times. It defined that optimal time measuring induced activity when working with short-life isotope 239U, 30 minutes. influence effects...
The effect of H2SO4 and FeSO4 concentrations temperature on the efficacy decontamination spent ion-exchange resins was estimated. study performed model purposefully contaminated with hematite Co-57 radionuclide. It found that an increase in solution up to 50 °C addition increases by 1 M 2 solutions 1–2 orders magnitude, whereas factor value here is >103. Since under static conditions, secondary adsorption observed, extra washing 3 NaNO3 required. Decontamination dynamic conditions...
Abstract Ash and slag waste accumulated throughout the world in appreciable amounts are, essence, man-made deposits are of interest as a potential source critical elements, particular Sc, well raw materials for obtaining construction materials. Coals from Siberia Far East used fuel at thermal power plants (TPPs) Primorsky Territory Russia. These coals characterized by high Sc content. The content ash wastes landfills six TPPs Krai was determined neutron activation analysis with Cf-252...
The content of a number strategic metals (Au, Sc, La, Sm, Eu, Dy) at the level comparable to their average contents in graphite-bearing rocks south Russian Far East was determined by method instrumental neutron activation analysis (INAA) on an original device with radionuclide source based 252 Cf. A key advantage INAA difficult-to-dissolve carbon-containing materials is non-destructive character method. proposed methodological approach avoids complex procedure sample decomposition, analyte...
The results of dosimetric measurements which were carried out on the territory former Novotroitsk mining department quarry (Baley, Zabaykalsky region) are obtained. map radioactive contamination is presented. A number objects explored area where gamma ray dose ambient equivalent exceeds maximum permissible level 0.60 mSv/h identified. specific effective activity and chemical composition a soil sample taken at one contaminated sites determined. It detected that main source radioactivity 232...
The possibility of determining the scandium content in ash and slag waste monitoring effectiveness operations processing by method instrumental neutron activation analysis was shown. elemental composition from thermal power plants intermediate products their are presented. An increased magnetic fraction established.
