The results of the research of the adsorption
capacity of a number of sorbents of natural and synthetic
origin for ammonium ions have been clustered. The
natural zeolite of the Sokyrnytsia deposit, a synthetic
sorbent based on the fly ash of Dobrotvir state district
heat power plant, Al2O3, SiO2, as well as some types of
soil: sandy soil, black soil, and clay were used in the
research. Equations describing the regularities of adsorption
processes depending on the type of sorbent were
obtained. According to the obtained dendrograms, two
main clusters of sorbents were identified. The statistical
parameters of the process and the significance of the
obtained results were calculated. The coefficient of
determination of the experimental data was 0.67–0.99,
the standard deviation was 0.017–0.026.
