Show Detailed Complexation Query Results


Surface Complex Formation Data:

Mineral: Goethite
Reference: SWM09
SCM Type: DDL - Diffuse Double Layer
Ligand: SO4<2-> - sulfate
Site Type: »Fe(w)-OH
Equation: »Fe(w)-OH + SO4<2-> + 2 H<1+>  ⇔  »Fe(w)-HSO4 + H2O
LogK: 13.02        LogK°I=0 (Conversion to I = 0):   13.02         LogK2.31 nm−2 (SSD-normalized):   13.70
Experiment: Batch Sorption Experiments
Ionic Strength: 0.0 mol/L
Temperature: 298.15 K
pH Range: 3 - 9
Fit Method: FITEQL
Comment: SO4 concentration of 0.776 mmol/kg;

1.31 g/kg Goethite;

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