Show Detailed Complexation Query Results


Surface Complex Formation Data:

Mineral: Ferrihydrite
Reference: SWM03
SCM Type: DDL - Diffuse Double Layer
Ligand: Pb<2+> - lead
Site Type: »Fe(w)-OH
Equation: »Fe(w)-OH + Pb<2+>  ⇔  »Fe(w)-O-Pb<1+> + H<1+>
LogK: 2.03        LogK°I=0 (Conversion to I = 0):   2.03         LogK2.31 nm−2 (SSD-normalized):   4.23
Experiment: Batch Sorption Experiments
Ionic Strength: 0.0 mol/L
Temperature: 298.15 K
pH Range: 3 - 6
Fit Method: FITEQL
Comment: Pb conc. of 9.66 µmol/kg, Fe concentration of 5.0 mmol/kg; no convergence of K2INT for this data so it was fixed at this value for consistency between results
