Physico-chemical properties and ecological aspect of crystalline iron (III) orthovanadate, iron (III), copper (II) and lead (II) metavanadate

In the work, iron (III) orthovanadate, iron (III), copper (II) and lead (II) metavanadates were obtained, the ratio of the obtained substances to concentrated acids – sulfuric, hydrochloric, nitric and orthophosphoric, alkalis, aqueous solutions of chlorine, bromine and iodine, some chalcogens, aluminum and magnesium oxides was studied. Melting temperatures, densities of crystalline substances, solubility in water have been experimentally determined. IR spectroscopic analysis of compounds by the method of disturbed total internal reflection was carried out for the first time. Based on the data obtained, conclusions are drawn about the structure and chemical properties of substances, as well as the most dangerous compounds obtained by interacting with acids, alkalis and halogens.
