| Comment: |
protonation of the singly and triply coordinated sites to form ≡FeOH2+0.5 and ≡Fe3OH+0.5 are described by a single pKa, which was set to the measured isoelectric point of the goethite; SSD (Fe-singly) was computed using ns = (STAN)/(1018aSA), where AN is the Avogadro constant; SSD (Fe-triply) taken from [TE02] and [AAFLA05], the inner-Helmholtz capacitance C1 was optimized in FITEQL using the Sb(V) adsorption envelop data; C2 = 5 F/m² [AAFLA05] |
