Surface Complex Formation Data:

Mineral: Goethite
Reference: S05
SCM Type: TL - Triple Layer
Ligand: HS<1-> - hydrogensulfid
Site Type: »Fe-OH
Equation: »Fe-OH + HS<1-> + H<1+>  ⇔  »Fe-OH2-HS
LogK: 14.7         LogK2.31 nm−2 (SSD-normalized):   15.64
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+> + HS<1-> = »Fe-OH2-HS logK = 8.3 »Fe-OH + H<1+> = »Fe-OH2<1+> -pK1 = logK = 6.4 sum »Fe-OH + HS<1->+ H<1+> = »Fe-OH2-HS logK= 8.3+6.4 = 14.7
