Surface Complex Formation Data:

Mineral: Goethite
Reference: SWM09
SCM Type: DDL - Diffuse Double Layer
Ligand: Cd<2+> - cadmium
Site Type: »Fe(s)-OH
Equation: »Fe(s)-OH + Cd<2+> + SO4<2->  ⇔  »Fe(s)-OH-CdSO4
LogK: 9.45        LogK°I=0 (Conversion to I = 0):   9.45         LogK2.31 nm−2 (SSD-normalized):   8.48
Experiment: Batch Sorption Experiments
Ionic Strength: 0.0 mol/L
Temperature: 298.15 K
pH Range: 5 - 8
Fit Method: FITEQL
Comment: Cd concentration of 71.0 µmol/kg,

SO4 concentration of 5.23 mmol/kg;

1.44 g/kg Goethite;

no convergence of this value so it was fixed at the weighted average for consistency
