Surface Complex Formation Data:

Mineral: Goethite
Reference: S05
SCM Type: TL - Triple Layer
Ligand: Rb<1+> - rubidium
Site Type: »Fe-OH
Equation: »Fe-OH + Rb<1+>  ⇔  »Fe-O-Rb + H<1+>
LogK: -8.8         LogK2.31 nm−2 (SSD-normalized):   -7.86
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-> + Rb<1+> = »Fe-O-Rb logK = 3.2 »Fe-OH = »Fe-O<1-> + H<1+> pK2 = -logK = 12.0 sum »Fe-OH +Rb<1+> = »Fe-O-Rb + H<1+> logK=3.2-12.0 = -8.8
