Show Detailed Complexation Query Results


Surface Complex Formation Data:

Mineral: Ferrihydrite
Reference: SWM03
SCM Type: DDL - Diffuse Double Layer
Ligand: Cd<2+> - cadmium
Site Type: »Fe(s)-OH
Equation: »Fe(s)-OH + Cd<2+>  ⇔  »Fe(s)-O-Cd<1+> + H<1+>
LogK: -0.17        LogK°I=0 (Conversion to I = 0):   -0.17         LogK2.31 nm−2 (SSD-normalized):   -0.08
Experiment: Batch Sorption Experiments
Ionic Strength: 0.0 mol/L
Temperature: 298.15 K
pH Range: 4 - 8
Fit Method: FITEQL
Comment: 3-site model; Cd conc. of 0.949 µmol/kg, Fe concentration of 10.3 mmol/kg; no convergence of this value so it was fixed at this value to achieve consistency between results
