Sorption of H4SiO4 (including experiments as a function of time, KdKd measurement with different m/vm/v 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 FeH2SiO−4, are needed to describe properly the experimental observations.
This figure represents experimental sorption edges of H4SiO4 on goethite, hematite, and magnetite, as well as calculations done with DDL model to accounts for the experimental observations.Figure optionsDownload as PowerPoint slide
