Features of the Sorption Process of Polyvalent Metal Cations in Soils

Abstract

The issue of migration and accumulation of harmful and toxic compounds in soils is considered. Particular attention is paid to the study of the rate of ion-exchange process of cations of copper, iron, zinc, aluminum on humic acids, since these elements constitute a significant mass of harmful emissions from industrial enterprises in the form of drainage effluents to be cleaned. The results of studies of mass transfer processes in soils for various compounds are presented. An approach is proposed based on the calculation of the average dynamic value of the charge of a polyvalent metal cation extinguished when interacting with a specific sorbent, which allows a predictive estimate of the migration and accumulation of this cation within the spill of its salt solution on the soil.
