Surface area of ferrihydrite consistently related to primary surface charge, ion pair formation, and specific ion adsorption
(2020-01-20)
The specific surface area (SSA) of metal oxides is pivotal for scaling of surface phenomena. For ferrihydrite (Fh), the SSA can be assessed by probing the surface with ions that specifically adsorb (e.g. protons or phosphate). ...
