Abstract


Materials based on sulfur nanoparticles are used in the preparation of composites, in construction, agriculture. The results of the study of the process of obtaining sulfur nanoparticles by deposition of inorganic and organic acids from an aqueous solution of calcium polysulfide based on lump sulfur of LLC "Gazprom Neftekhim Salavat" are presented. The influence of the nature and concentration of acid precipitators on the size of sulfur nanoparticles was established. Optimal conditions for the formation of sulfur nanoparticles were determined. It is experimentally proved that sulfur nanoparticles and its dispersion with different alcohols at the early stages of germination of wheat shoots and grains exhibit biological activity. The optimal concentration of sulfur to stimulate the growth of shoots and roots of wheat was established.
