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.

The article discusses the issue of creating a software interface for developing fuzzy inference systems using the ScikitFuzzy library. With the help of the developed software module, a computational experiment was carried out to calculate the fuzzy output of the values of technological parameters for a fourcase evaporator unit, which is part of the evaporation shop of chlorine production.
