Show Detailed Complexation Query Results

Surface Complex Formation Data:

Mineral:	Quartz
Reference:	ZB04b
SCM Type:	NE - Non-electrostatic
Ligand:	Pu<4+> - plutonium(IV)
Site Type:	»Si-OH
Equation:	»SiOH + Pu<4+> + H2O ⇔ »SiO-PuO<1+> + H<1+>
LogK:	2.32 ± 0.89
Experiment:	Batch Sorption Experiments
Ionic Strength:
Temperature:	298.15 K
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; surface complexation to aluminosilicate >SiOH or >AlOH reactive sites is considered equivalent to the reactivity of aluminum oxide and silica reactive sites.
