Surface Complex Formation Data:

Mineral: Magnetite
Reference: S05
SCM Type: TL - Triple Layer
Ligand: NO2<1-> - nitrite
Site Type: »Fe-OH
Equation: »Fe-OH + NO2<1-> + H<1+>  ⇔  »Fe-OH2-NO2
LogK: 10.3         LogK2.31 nm−2 (SSD-normalized):   11.24
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+> + NO2<1-> = »Fe-OH2-NO2 logK = 5.7 »Fe-OH + H<1+> = »Fe-OH2<1+> -pK1 = logK = 4.6 sum »Fe-OH + NO2<1->+ H<1+> = »Fe-OH2-NO2 logK=5.7+4.6 =10.3
