Surface Complex Formation Data:

Mineral: Magnetite
Reference: S05
SCM Type: TL - Triple Layer
Ligand: Br<1-> - bromide
Site Type: »Fe-OH
Equation: »Fe-OH + Br<1-> + H<1+>  ⇔  »Fe-OH2-Br
LogK: 7.4         LogK2.31 nm−2 (SSD-normalized):   8.34
Experiment: Literature
Ionic Strength: 1.0 mol/L
Temperature: 298.15 K
Fit Method: Unknown
Comment: calculation from literature values with standard SSA and SSD at ionic strength of 1M »Fe-OH2<1+> + Br<1-> = »Fe-OH2-Br logK = 2.8 »Fe-OH + H<1+> = »Fe-OH2<1+> - pK1 = logK = 4.6 sum »Fe-OH + Br<1->+ H<1+> = »Fe-OH2-Br logK= 2.8+4.6 = 7.4
