Surface Complex Formation Data:

Mineral: Goethite
Reference: S05
SCM Type: TL - Triple Layer
Ligand: Cl<1-> - chloride
Site Type: »Fe-OH
Equation: »Fe-OH + Cl<1-> + H<1+>  ⇔  »Fe-OH2-Cl
LogK: 9.6         LogK2.31 nm−2 (SSD-normalized):   10.54
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+> + Cl<1-> = »Fe-OH2-Cl logK = 3.2 »Fe-OH + H<1+> = »Fe-OH2<1+> -pK1 = logK = 6.4 sum »Fe-OH + Cl<1->+ H<1+> = »Fe-OH2-Cl logK= 3.2+6.4 = 9.6
