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
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
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
Effective purification of water from iron lons and potentially pathogenic microorganisms using a montmorillonite composite sorbent
The use of the developed composite sorbent based on the plant wastes (sunflower seed husks) and montmorillonite clay was shown to be highly effective for water purification from iron ions and potentially pathogenic microorganisms. It was shown experimentally that the developed composite sorbent at concentrations of up to 50 mg/L is capable of purifying water from iron ions under static and dynamic condition

Adsorption of methylene blue on the composite sorbent based on bentonite-like clay and hydroxyapatite
The adsorption of methylene blue from model aqueous solutions on bentonite-like clay, hydroxyapatite, and a composite sorbent has been investigated. The kinetic and thermodynamic parameters of adsorption in the temperature range 298-333 К have been calculated. The process is found to obey Langmuir isotherm equation. It is spontaneous but slightly endothermi

Material composition and colloid-chemical properties of natural and modified montmorillonite clays
There is determined the dependence of colloid-chemical properties of the natural and modified montmorillonite clays from “Polyana” deposit in Shebekinsky district, Belgorod Region, Russian Federation, on their material composition, i.е. on their chemical, mineral and granulometric compositio
