Surface Complex Formation Data:

Mineral: Hematite
Reference: MF99
SCM Type: DDL - Diffuse Double Layer
Ligand: La<3+> - lanthanum
Site Type: »Fe-OH
Equation: »Fe-OH + La<3+> + H2O  ⇔  »Fe-O-La(OH)<1+> + 2 H<1+>
LogK: -8.8 ± 0.2         LogK°I=0 (Conversion to I = 0):   -8.05         LogK2.31 nm−2 (SSD-normalized):   -7.86
Experiment: Batch Sorption Experiments
Ionic Strength: 0.1 mol/L NaNO3
Fit Method: FITEQL
Comment: surface loading ratio R=[La3+]/[FeOH]total=0.12; only in combination with ºFeOH + La3+ = ºFeO-La2+ + H+
