Show Detailed Complexation Query Results


Surface Complex Formation Data:

Mineral: Goethite
Reference: RL98
SCM Type: TL - Triple Layer
Ligand: Cu<2+> - copper
Site Type: »Fe(w)-OH
Equation: »Fe(w)-OH + Cu<2+>  ⇔  »Fe(w)-O-Cu<1+> + H<1+>
LogK: 2.667        LogK°I=0 (Conversion to I = 0):   2.67         LogK2.31 nm−2 (SSD-normalized):   7.43
Experiment: Sorption Isotherms
Ionic Strength: 0.0 mol/L NaClO4
pH Range: 6,07, 5,07, 4,07
Fit Method: FITEQL
Comment: I = 0.01 and 0.1 M; experimental data can be replicated well by assuming two binding sites, WSOS/DF=16.7; fit with assumption of =FeOCu+ and =FeOCuOH
