Surface Complex Formation Data:

Mineral: Gibbsite
Reference: S05
SCM Type: TL - Triple Layer
Ligand: NO3<1-> - nitrate
Site Type: »Al-OH
Equation: »Al-OH + NO3<1-> + H<1+>  ⇔  »Al-OH2-NO3
LogK: 9.7         LogK2.31 nm−2 (SSD-normalized):   8.31
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+> + NO3<1-> = »Al-OH2-NO3 logK = 2.7 »Al-OH + H<1+> = »AL-OH2<1+> - pK1 = logK = 7.0 sum »AlL-OH + NO3<1->+ H<1+> = »Al-OH2-NO3 logK= 2.7+7.0 = 9.7
