Surface Complex Formation Data:

Mineral: Corundum
Reference: S05
SCM Type: TL - Triple Layer
Ligand: NO2<1-> - nitrite
Site Type: »Al-OH
Equation: »Al-OH + NO2<1-> + H<1+>  ⇔  »Al-OH2-NO2
LogK: 12.2         LogK2.31 nm−2 (SSD-normalized):   10.81
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 »Al-OH2<1+> + NO2<1-> = »Al-OH2-NO2 logK = 5.6 »Al-OH + H<1+> = »Al-OH2<1+> - pK1 = logK = 6.6 sum »Al-OH + NO2<1->+ H<1+> = »Al-OH2-NO2 logK= 5.6+6.6 = 12.2
