RES³T - Rossendorf Expert System for Surface and Sorption Thermodynamics

Show Detailed Complexation Query Results


Surface Complex Formation Data:

Mineral: Ferrihydrite
Reference: BL81a
SCM Type: TL - Triple Layer
Ligand: Cd<2+> - cadmium
Site Type: »Fe-OH
Equation: »Fe-OH + Cd<2+> + H2O  ⇔  »Fe-O-Cd(OH) + 2 H<1+>
LogK: -10.5        LogK°I=0 (Conversion to I = 0):   -10.29
Experiment: Batch Sorption Experiments
Ionic Strength: 0.1 mol/L NaNO3
Ligand Concentration Range: 1E-7 mol/L
Fit Method: graphic extrapolation
Comment: logK=-11.2 for [Cd]=5E-5M; based on [DJL78] but there only amorphous silica and alumina; no site density and surface protolysis data
