Surface Complex Formation Data:

Mineral: Ferrihydrite
Reference: SJ91
SCM Type: TL - Triple Layer
Ligand: Ag<1+> - silver
Site Type: »Fe-OH
Equation: »Fe-OH + Ag<1+> + H2O  ⇔  »Fe-O-Ag(OH)<1-> + 2 H<1+>
LogK: -12.3 ± 0.8         LogK°I=0 (Conversion to I = 0):   -12.41         LogK2.31 nm−2 (SSD-normalized):  
Experiment: Mean of Different Sources
Ionic Strength: 0.1 mol/L
Fit Method:
Comment: recalculation from literature values [DL78a] (ferrihydrite) in an effort to remove the uncertainties associated with SSD, same log K also for goethite, log K differs significantly from the measured values of [DL78a], reason not clear
