Abstract:

The use of natural and synthetic sorbents for polluted water treatment from heavy metals and oil products is one of the most practical methods of natural and waste water treatment. The main advantages of adsorption of polluted water treatment with sorbents are a sufficiently high degree of purification, costeffectiveness and the possibility of repeated use of the sorbent. The use of natural renewable raw materials is of great interest in the development of commercially available complex sorbents capable of sorbing both inorganic compounds and organic pollutants (petroleum products) and facilit

Abstract:

In this article, we present polymer non-woven fabrics with the addition of carbon sorbents being tested to estimate the breakthrough time and efficient protection against vapors present in smog. For this purpose, three substances were selected, which constitute an inhalation hazard and are smog components: cyclohexane, toluene, and sulfur dioxide. It was demonstrated that an increased quantity of carbon sorbent in polymeric filters significantly prolongs the breakthrough time. However, high sorbent quantities may increase the filter surface mass and air flow resistance. To optimize the protect

Abstract:

Carbon capture and storage (CCS) offers a possible solution to curb the CO<sub>2</sub> emissions from stationary sources in the coming decades, considering the delays in shifting energy generation to carbon neutral sources such as wind, solar and biomass. The most mature technology for post-combustion capture uses a liquid sorbent, amine scrubbing. However, with the existing technology, a large amount of heat is required for the regeneration of the liquid sorbent, which introduces a substantial energy penalty. The use of alternative sorbents for CO<sub>2</sub> capture, such as the CaO–CaCO<sub

Abstract:

The results of studies of the carbon sorbent adsorption properties by atomic absorption spectrometry are presented. Carbon sorbent was obtained by graphite nitrate cointercalation compound thermal expansion at 900 °C. It is shown that the Freundlich, Langmuir and Temkin equations adequately describe the adsorption of the studied metal ions by a carbon sorbent. The carbon sorbent after the adsorption of heavy metal ions was studied using energy-dispersive X-ray spectrometry and X-ray powder diffraction. The limit values were fixed for the adsorption capacity of the sorbent relative to Cu2+, Ni2
