STUDY OF VARIOUS FORMES OF IRON COMPOUNDS AND THEIR ROLE IN PROCESS OF SOIL FORMATION

The existing discrepancy between the chemical methods used for separating metal compounds (for example, iron) from soils and their physical interpretation (radiographic methods) because of the ambiguous relationship between the solubility of metal compounds and the state of their crystalline structure, as well as the terminology on the characteristics of extracts, does not allow specialists and experts in the field of soil science unambiguously interpret the experimental data on the composition of soils, including for reasons of their involvement with heavy compounds of metals. To eliminate the existing inconsistencies, an automated installation was set up in the laboratory of the FTT of the YSTU and multiple measurements of samples of soils and microorganisms of plant and animal life confirming the magneto-ordering of iron compounds were made. The possibility of independent control over the effect of chemical extracts on complex soil samples allowed the development of methods that to some extent dissolve individual mineral forms of iron-oxalate (Tamm) and dithionite-sodium (Mera-Jackson) methods. It is shown that soil formation is accompanied by differentiation of magnetic properties along genetic horizons. The pondentometer method, or otherwise the Faraday-Sexamite method, is most suitable for studying inhomogeneous magnetic characteristics, has a high accuracy of results, excludes the influence of environmental impurities to the iron. The proposed scientific approach for more correct interpretation of data (in relation to soil analysis) obtained by various physical and chemical methods is the best for achieving high accuracy of measurement results, in which the influence of environmental impurities on the iron is excluded. This study may be of interest to specialists and scientists in the field of physical and inorganic chemistry, inorganic substances technology, as well as in the field of environmental protection, which emphasizes the relevance of the article.Forcitation:Babanin V.F., Boychenko V.O., Mineeva N.S., Filatov A.V.
