Lavrynenko O. The Obtaining of the Composition Structured Systems Based on the Iron-Oxygen Minerals, Their Structure and Properties

The presented work provides a basis for the purposeful obtaining of the iron-oxygen species particles by the method of rotation-corrosion dispergation based on the principle of iron (steel) electrode corrosion when its surface contacts either with air or dispersion medium. That provides for dosated introduction of oxygen and ferrous iron on the iron (steel) surface - dispersion medium - air interface and creates the condition of the heterogeneous particle growth. The colloid-chemical mechanisms and optimal conditions of the formation of iron oxide and hydroxide, iron spinel ferrite and core&shell are determined when the method of rotation-corrosion dispergation is realized. The influence of the physicochemical factors on the phase composition, size, structure and properties are investigated. It is processed the complex method of the separation of micronsized mineral alloys of iron oxides and hydroxides when the individual particles are obtained. The biological activity of the nanosized particles is investigated. The iron-oxygen particles tested are recognized as capable of creating nanosized magnetic holder and they can be of interest as perspective means for the target drug delivery and therapy of different pathological states connected with cell and tissue oxidative damages.
