Surface Complexation Modeling – Hydrous Ferric Oxide
In this chapter we survey and synthesize available information on the major physical-chemical properties of hydrous ferric oxide (HFO). After examining the structure and composition of HFO, we present published data for surface area, site densities, and surface acid-base properties. Our main purpose is to obtain best estimates for the surface properties of HFO and provide a sense for the consistency of the corresponding experimental data.
