Surface Complex Formation Data:

Mineral: Alumina
Reference: ZB04b
SCM Type: NE - Non-electrostatic
Ligand: Pu<4+> - plutonium(IV)
Site Type: »Al-OH
Equation: »Al-OH + Pu<4+> + H2O  ⇔  »Al-O-PuO<1+> + 3 H<1+>
LogK: 5.95 ± 0.47         LogK2.31 nm−2 (SSD-normalized):   4.56
Experiment: Batch Sorption Experiments
Ionic Strength:
Temperature: 298.15 K
Ligand Concentration Range: 6E-10. 2E-10. 6E-08 mol/L
Fit Method: FITEQL
Comment: average non-electrostatic SC constant for aluminosilicates of 4 curves from [RBAB91], [AOTKA82] and [S83c]; standard deviation relate to the differences in fitted logK constants from the various batch sorption data sets; IS was 0.01 and 0.1 M; surface complexation to aluminosilicate >SiOH or >AlOH reactive sites is considered equivalent to the reactivity of aluminum oxide and silica reactive sites.
