Oliynyk V. Modification of colloid-chemical properties of ferrioxide-silicate systems with micro- and nanoparticles

Dissertation is devoted to studying of modification features of micro- and nanoparticle influence on colloid-chemical properties of ferrioxide-silicate materials and systems based on them and to studying of colloid-chemical and nanostructure transformation processes of such systems and materials. Influence of micro- and nanoparticles on modification of colloid-chemical properties of ferrioxide-silicate materials is considered in their mechanochemical dispersion processes. The principles of controlling mechanochemical dispersion of such materials in a presence of alkaline silicate nanoadditives have been developed. Colloid-chemical fundamentals of controlling the processes of receiving carbonized nanostructured ferric sorption materials with specified properties were developed. It is shown, that the main effect on colloid-chemical properties of natural carbonic ferrioxide-silicate materials has the presence of mineral and carbonic micro- and nanoparticles in their source aluminosilicate matrix. It is determined that such materials have good sorption properties towards harmful toxic anthropogenic pollutants and they can be used in purification of different dispersed systems, for example, therapeutic clay-carbonic peloid compositions. It is shown that the presence of micro- and nanoparticles in composition of such ferrioxide-silicate systems like clay-carbonic peloid compositions can effect their colloid-chemical properties materially and improve their biomedical activity in two or three times.
