Summary:Selenium colloidal solutions with particles ranging from 20 to 100 nm were obtained by mechanical dispersion of selenium pellets in water at frequency of 100 Hz. It is shown that the properties of selenium colloidal solutions prepared by mechanical dispersion depend on the material of the vessel in which they are obtained. The selenium solutions obtained in plastic vessels have acidic properties, while in glass vessels they are alkaline. Upon evaporation of colloidal solutions, highly anisotropic dendritic structures are formed, which may indicate anisotropy of the formed nanoparticles. The aqueous colloidal system of nanoscale selenium obtained by mechanical dispersion in concentrations physiologically significant for plants has a positive effect on the seeds of agricultural crops. Selenium colloidal solutions have greater antioxidant activity compared to sodium selenite with lower toxicity values.
