Surface Complex Formation Data:

Mineral: Hematite
Reference: MF99
SCM Type: CC - Constant Capacitance
Ligand: La<3+> - lanthanum
Site Type: »Fe-OH
Equation: »Fe-OH + La<3+>  ⇔  »Fe-O-La<2+> + H<1+>
LogK: -1.1 ± 0.3         LogK°I=0 (Conversion to I = 0):   -0.24         LogK2.31 nm−2 (SSD-normalized):   -0.16
