The data obtained show that at pH 7 copper(II) ions are adsorbed on a SiO2 surface as polymeric species of hydroxide nature. The structure of these species is similar to that of the bulk amorphous copper hydroxide. The amorphous state of supported Cu(OH)2 is caused by a small (ca. 11 ร ) size of the
The surface complexation model is used to describe sorption experiments of inorganic mercury(II) in the presence of an amorphous silica, Aerosil 200, or an iron (hydr)oxide, the goethite โฃ-FeOOH (Bayferrox 910). In the simulations, one assumes the formation of a monodentate surface complex 'SOOHg ุ
