The results of the study of the adsorption capacity of a number of sorbents of natural and synthetic origin with respect to iron ions have been clustered. The sorption capacity of the following sorbents was studied: natural zeolite of the Sokyrnytsia deposit, synthetic sorbent based on the ash of Doborotvir heat power plant, Al2O3, SiO2, as well as some types of soils: sandy soil, black soil and clay. Equations describing the regularities of adsorption processes depending on the type of sorbent are obtained. According to the obtained dendrograms of the adsorption process, two main clusters of sorbents were identified. The statistical parameters of the process and the significance of the obtained results are calculated. The coefficient of determination of experimental data was 0.87– 0.99, the standard deviation was 0.017–0.026.
