Abstract
Thereby the article is devoted to the research of the impact of the geotechnical system on the environment (soil cover). A methodology for studying the concentration of salts in the process of soil salinization has been developed. The method of simplex-lattice interaction planning in multicomponent systems constructing the full-composition-property diagram by matrix was used. The results of a chemical-analytical study of the content of pollutants, simplex-lattice planning ofthe effect of salt components on the soil, are presented giving a composition-property diagram of the NaCl (X1) -MgSO4 (X2) -CaSO4 (X3) system. It is established that the highest degree of salinity is achieved with the ratio of components X1: X2: X3 = 10: 60: 30. In the sulfated-enriched area, the degree of salinity is the highest (up to 99.8%): while in the chloride corner the degree is lower (to 70-80%), which is caused by the greater solubility of alkali metal chlorides (in particular, sodium chloride NaCI) and more intensive washout of chlorides in comparison withsulphates. The practical value of the work is development of recommendations for reducing the salinization of the lithosphere by studying the system of natural minerals gallite - NaCI MgSO4 and calcium sulfate CaSO4.
