Abstract: The sorption characteristics and diffuse reflectance and EPR spectra of osmium surface complexes showed that Os⁸⁺ and Os⁶⁺ in OsO₄ and K₂[OsO₂Cl₄], respectively, react with mercaptopropyl groups, whereas Os⁴⁺ in K₂[OsCl₆] reacts with aminopropyl groups covalently bound to a silica gel surface.
