Increasing the production efficiency of chrysotile cement products

Improving the efficiency of chrysotile-cement products is achieved by changing the raw materials with additives, changing their structure and properties, generating new kinds of chrysotile-cement productsnoBelgorod State Universit

Some problems of environmental chemistry and their solutions

It is known that the increasing amount of CO2 emissions of anthropogenic character leads to a disruption of the thermal balance of the Earth and is one of the reasons for the greenhouse effect. In our opinion, the future solution of the greenhouse effect problem consists in the return to the natural cycle of the element carbon in nature accompanied by the scientifically sound creative activity of the humanity. Creation of green planting with high photosynthetic properties will enable to utilize carbon dioxide by turning it into organic substance

Effects of nanodispersed iron on the morphofunctional parameters of the blood system

The effects of nanodispersed iron forms on the morphology and function of the blood system were studied. Maghemite and lepidocrocite caused a leukocytic shift towards segmented neutrophil forms, reduction of lymphocyte rigidity, and stimulated their compactization. In addition, the counts of small hyperchromatic erythrocytes with high rigidity increased in the blood flow. The results indicated that a single dose of nanodispersed iron-containing drugs improved the blood respiratory function and its microrheolog

Environmental aspects of the clay use in industrial and agricultural production

In the course of the last 10 years the scientists from the Chair of General Chemistry of the Belgorod State National Research University have been carrying out an active research in the development of efficient sorbents on the base of native montmorillonite clays in the region in order to purify natural and industrial water

The etiological structure of mass diseases with young gastro and respiratory syndrome

Etiology gastroenteritis and pneumonia animals studied complex, on the basis of epizootic, clinical, pathological data, bacteriological results, serology, hematology, immunobiochemical research method

The influence of the concentration of montmorillonite containing sorbent and pH of the culture medium on the antibiotic sensitivity of Escherichia coli, as well as the effect of ground on growth of Escherichia

The aim of this work was the comparative sensitivity test of E. coli to enrofloxacin and doxycycline and bactericidal action of montmorillonite containing sorbent and its combination with enrofloxacin, as well as the influence of the concentration of the enriched montmorillonite containing sorbent and pH of the culture medium on the antibiotic sensitivity of Escherichia coli. The sensitivity test of Escherichia coli to enrofloxacin, and the combination of enrofloxacin with sorbent was performd by the method of double serial dilutions of drugs in a liquid culture mediu

Investigation of sorption of Cu₂₊, Zn₂₊ and Cd₂₊ ions by a composite adsorbent obtained from bentonite-like clay and hydroxyapatite

The article analyses the results of the measuring of pHpzc (point zero charge) of the surface of adsorbents by potentiometric titration are presente

Adsorption of glyphosate on carbon-containing materials

A study is performed of the adsorption of glyphosate on carbon-containing materials obtained from pyrolysis products of sugar cane waste and commercial coconut activated carbon. The adsorption capacity of the materials with respect to glyphosate was determined using a variety of experimental model

Effect of the acidic and alkaline activation of bentonite-like clays on sorption properties in relation to Fe³⁺ ions under static conditions

A study is performed of the effect the means of activation of bentonite-like clays (acidic, alkaline, combined) have on the adsorption characteristics of Fe³⁺ ions under static conditions. The mechanism of the acidic and alkaline activation of montmorillonite is identified and found to depend on the concentration of the activating agen

On the adsorption mechanism of copper ions on bentonite clay

The adsorption of copper ions on bentonite clay was studied as a function of the pH of the medium, contact time, and temperature. A comparative study of the applicability of the Langmuir and Freindlich adsorption models for the description of the experimental adsorption isotherms of Cu²⁺ was carried ou
