Show Detailed Complexation Query Results


Surface Complex Formation Data:

Mineral: amorphous Silica
Reference: ZB04b
SCM Type: NE - Non-electrostatic
Ligand: Am<3+> - americium
Site Type: »Si-OH
Equation: »SiOH + Am<3+>  ⇔  »SiO-Am<2+> + H<1+>
LogK: 0.7 ± 0.1
Experiment: Batch Sorption Experiments
Ionic Strength:
Temperature: 298.15 K
Ligand Concentration Range: 5E-10. 2.3E-09. 1E-08 mol/L
Fit Method: FITEQL
Comment: average non-electrostatic SC constant for aluminosilicates of 4 curves from [RBAB91], [AOTKA82] and [MSO92]; 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.
