Surface Complex Formation Data:

Mineral: Anatase
Reference: S05
SCM Type: TL - Triple Layer
Ligand: NH4<+> - ammonium
Site Type: »Ti-OH
Equation: »Ti-OH + NH4<+>  ⇔  »Ti-O-NH4 + H<1+>
LogK: 2.9         LogK2.31 nm−2 (SSD-normalized):   3.24
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 »Ti-O<1-> +NH4<1+> = »Ti-O-NH4 logK = 12.1 »Ti-OH = »Ti-O<1-> + H<1+> pK2 = -logK = 9.2 sum »Ti-OH + NH4<1+> = »Ti-O-NH4 + H<1+> logK=12.1-9.2 = 2.9
