The adsorption behavior of selenate (SeO 4 ) on goethite has been studied under a wide range of conditions. SeO 4 adsorption has been compared with the binding of SO 4 . The experimental results are interpreted in view of very recent spectroscopic work on the speciation and coordination of adsorbed

The coordination and speciation of selenate (SeO(4)) and sulfate (SO(4)) on goethite and Al oxide were studied using Raman and ATR-FTIR spectroscopy. Raman spectra were collected from pastes of suspensions containing 4 mM SeO(4) or SO(4). For SO(4), complementary data were collected by ATR-FTIR spec
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 β£-FeOOH (Bayferrox 910). In the simulations, one assumes the formation of a monodentate surface complex 'SOOHg Ψ
