Surface Complex Formation Data:

Mineral: Magnetite
Reference: S05
SCM Type: TL - Triple Layer
Ligand: TMA<1+> - tetramethylammonium
Site Type: »Fe-OH
Equation: »Fe-OH + TMA<1+>  ⇔  »Fe-O-TMA + H<1+>
LogK: -6.9         LogK2.31 nm−2 (SSD-normalized):   -5.96
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-O<1-> +TMA<1+> = »Fe-O-TMA logK = 3.4 »Fe-OH = »Fe-O<1-> + H<1+> pK2 = -logK = 10.3 sum »Fe-OH + TMA<1+> = »Fe-O-TMA + H<1+> logK=3.4-10.3 = -6.9
