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(s1)-OH
Equation: »Fe(s1)-OH + Pb<2+>  ⇔  »Fe(s1)-O-Pb<1+> + H<1+>
LogK: 7.2        LogK°I=0 (Conversion to I = 0):   7.20
Experiment: Batch Sorption Experiments
Ionic Strength: 0.0 mol/L
Temperature: 298.15 K
pH Range: 3 - 6
Fit Method: FITEQL
Comment: 3-site model (third higher affinity site); Pb conc. of 9.86 µmol/kg, Fe concentration of 1.09 mmol/kg; no convergence of this value so it was fixed to achieve consistency between results
