Surface Complex Formation Data:

Mineral: Alumina
Reference: ZB04b
SCM Type: NE - Non-electrostatic
Ligand: Eu<3+> - europium(III)
Site Type: »Al-OH
Equation: »Al-OH + Eu<3+>  ⇔  »Al-O-Eu<2+> + H<1+>
LogK: 2.29 ± 0.45         LogK2.31 nm−2 (SSD-normalized):   0.90
Experiment: Batch Sorption Experiments
Ionic Strength:
Temperature: 298.15 K
Ligand Concentration Range: 7E-09. 1E-08 mol/L
Fit Method: FITEQL
Comment: average non-electrostatic SC constant for aluminosilicates of 5 curves from [SEM81] and [NEA94]; standard deviation relate to the differences in fitted logK constants from the various batch sorption data sets; IS was 0.01, 0.1 and 0.5 M; surface complexation to aluminosilicate >SiOH or >AlOH reactive sites is considered equivalent to the reactivity of aluminum oxide and silica reactive sites.
