Adsorption of Lead Ions on Carbonaceous Sorbents of Nutshell Obtained from Secondary Raw Material

Treatment of Leachate by the Carbon Material Obtained From Polymer Fraction of Municipal Solid Waste

“…From July 2022 till January 2023 every month, we were sampling of leachate water from the storage tank of the leachate water on the territory of MSW landfill of Norio. Physical and chemical indices were measured in the field, and then in the laboratory, the determination of heavy metals (Pb, Cr, Cd, Hg) and microbiological indices (Total coliforms, E. coli) were carried out according to ISO methods [18][19][20][21].…”

Theoretical Aspects of Processes of Metal Particles Adsorption Inside Channels and on Surface of Carbon Sorbents

“…To carry out such processes, it is necessary to use filters obtained using, in particular, carbon materials [1][2][3][4][5][6][7][8][9][10][11][12]. The full cycle of the extraction process requires consideration of the separate stages.…”

“…With the use of sorbents, of course, the cost of obtaining highquality materials increases, and therefore obtaining cheap and accessible sorbents from the point of view of the technology for obtaining sorbents is essential. Cheap methods for obtaining sorbents within the framework of a single-phase technological process from recycled materials proposed in works [4][5][6][7][8][9], is a constantly urgent task. At the same time, the experimental studies carried out by the authors of works [4][5][6][7][8][9] show the need to develop theoretical models, within which it will be possible to evaluate, at least qualitatively, some CHEMICAL PROBLEMS 2022 no.…”

“…It is natural that the pattern of solvation of metal particles, on the one hand, and the deposition of solvated metal particles on the surface of the sorbent, on the other hand, are dependent on the ratio of various effects of interactions within such a system. Numerous experimental studies show that these processes actually occur in the systems under study [5][6]9].…”
