Show Detailed Complexation Query Results


Surface Complex Formation Data:

Mineral: Ferrihydrite
Reference: SWM03
SCM Type: DDL - Diffuse Double Layer
Ligand: Co<2+> - cobalt(II)
Site Type: »Fe(w)-OH
Equation: »Fe(w)-OH + Co<2+>  ⇔  »Fe(w)-O-Co<1+> + H<1+>
LogK: -3.01        LogK°I=0 (Conversion to I = 0):   -3.01         LogK2.31 nm−2 (SSD-normalized):   -0.81
Experiment: Batch Sorption Experiments
Ionic Strength: 0.0 mol/L
Temperature: 298.15 K
pH Range: 5 - 8
Fit Method: FITEQL
Comment: Co conc. of 1.72 and 17.2 µmol/kg, Fe concentration of 10.1 mmol/kg; no convergence of K2INT for this data so it was fixed at this value for consistency between results
