Surface Complex Formation Data:

Mineral: Ferrihydrite
Reference: MST95
SCM Type: NE - Non-electrostatic
Ligand: UO2<2+> - uranyl(VI)
Site Type: »X-OH
Equation: »X-OH + UO2<2+> + 3 H2O  ⇔  »X-OH2-UO2(OH)3<1-> + 2 H<1+>
LogK: -2.5        LogK°I=0 (Conversion to I = 0):   -2.29         LogK2.31 nm−2 (SSD-normalized):   -2.00
Experiment: Batch Sorption Experiments
Ionic Strength: 0.1 mol/L NaNO3
pH Range: 4-10
Fit Method: MINEQL
Comment: Adsorption species are from a goethite model by [T83]; binding constants were modified to account for the stronger adsorption by amorphous ferric oxyhydroxide. A log *β-value for UO2(OH)2 of -9.0 was chosen
