Abstract
Agro- and physico-chemical analysis of three types of soils was carried out. It has been shown that the pH value for dark gray soil is 5.5 and characterizes it as more acidic compared to gray soil (pH = 6.0) and black soil (rich soil) (pH = 6.5). Molecular masses and sizes of colloidal micelles of humic substances from soil samples were determined. It is shown that the size of humic micelles in three types of soils is different and is inversely related to pH -the lower the pH value, the larger the micelles. The presence of a direct relationship between the efficiency of immobilization of oil particles in soil and the size of micelles of humic structures was revealed. This factor determines the effectiveness of oil pollution remediation. New dependencies have been obtained that can be used to predict the consequences of oil pollution, as well as to develop a targeted action technology for soil cleaning. The prospects of using the scientific approach for practical purposes are shown. Knowing the obtained dependences, it is possible to control the formation of large micelles and create optimal technological conditions for the sorption of oil by particles in each type of soil. The results are of fundamental importance, contribute to the ecological chemistry of soils and contribute to an in-depth understanding of the interaction of bioremediates with oil.
