Analysis of the structures of mathematical models for studying the sorption properties of thermally modified sorbents of quartz, zeolite and shungite during the sorption of Сu2+
The analysis of the structures of mathematical models describing the process of sorption of Сu<sup>2+ </sup>was carried out, the coefficients of determination were determined, for the structures under consideration, cumulative diagrams of the processes of sorption of Сu<sup>2+ </sup>by thermally modified sorbents - quartz, zeolite and shungite - were analyzed.
