Comment: |
Ar-purged conditions; all data from [HV96]; SCM type: Three-Plane-Model (TPM) derived from 1-pK-model formulations [HV96]; Ionic strength 0.001, 0.01, 0.1 M NaNO3; total site density: 10%singly coordinated 021 sites and 90% triply coordinated 110 sites; protolysis constants adjusted slightly to meet present assumptions; protolysis equations: »FeOH2 1/2+ = »FeOH 1/2- + H+ and: »Fe3OH 1/2+ = »Fe3O 1/2- + H+; in the paper the equation not correct with »FeO3H 1/2- = »Fe3O 1/2- + H+ |
