Surface Complex Formation Data:

Mineral: Alumina
Reference: S05
SCM Type: TL - Triple Layer
Ligand: OH<1-> - hydroxyde
Site Type: »Al-OH
Equation: »Al-OH + OH<1-> + H<1+>  ⇔  »Al-OH2-OH
LogK: 17.5         LogK2.31 nm−2 (SSD-normalized):   16.11
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+> + OH<1-> = »Al-OH2-OH logK = 11.9 »Al-OH + H<1+> = »AL-OH2<1+> - pK1 = logK = 5.6 sum »Al-OH + OH<1->+ H<1+> = »Al-OH2-OH logK= 11.9+5.6 = 17.5
