Abstract
The method of high-performance liquid chromatography has been used to study the adsorption of stable silver nanoparticles, which were obtained by radiation-chemical synthesis in reverse micellar solutions of H2O + Ag+/Aerosol OT/isooctane composition. Adsorption was conducted on polar and nonpolar sorbents. It has been determined that almost all nanoparticles are retained on nonpolar sorbent C18; however, their binding is not strong. After accumulation of a particular amount of nanoparticles, they leave a column with effluent. It has been shown that the adsorption and optical properties of silver nanoparticles almost do not change after the adsorption-desorption cycle on C18. It has been determined that, on polar silica gel, the adsorption of silver nanoparticles proceeds less intensely (fewer than half of the particles move to the near-surface layer of the sorbent; however, their interaction with surface is very strong and they were not desorbed. For nanoparticles and the molecules of the micelle-forming agent Aerosol OT, adsorption isotherms have been plotted. Based on the obtained results, possible mechanisms of adsorption of nanoparticles on the surface of polar and nonpolar sorbents have been considered.
