Abstract: |
Sorption of H4SiO4 (including experiments as a function of time, Kd measurement with different m/ν ratios and sorption edges) onto different iron (hydro)oxides as goethite (α-FeOOH), hematite (α-Fe2O3), and magnetite (Fe3O4) has been studied with concentration of silicates under solubility limit. A surface complexation model has been used to account for sorption edge of silicates onto these iron oxide surfaces. It reveals that two types of surface complex namely ≡FeH3SiO4 and ≡FeH2SiO4−, are needed to describe properly the experimental observations. |
