Show Detailed Complexation Query Results

Surface Complex Formation Data:

Mineral:	Montmorillonite
Reference:	G17
SCM Type:	NE - Non-electrostatic
Ligand:	Pd<2+> - palladium
Site Type:	»X(s)-OH
Equation:	»X(s)-OH + Pd<2+> + 2 H2O ⇔ »X(s)-O-Pd(OH)2<1-> + 3 H<1+>
LogK:	-5.5 LogK°_I=0 (Conversion to I = 0): -5.50
Experiment:	Batch Sorption Experiments
Ionic Strength:	0.0 mol/L
Solid/Liquid Ratio:	1.0 g/L
pH Range:	3 - 9
Ligand Concentration Range:	1E-7 mol/L
