Show Detailed Complexation Query Results

Surface Complex Formation Data:

Mineral:	Ferrihydrite
Reference:	SWM03
SCM Type:	DDL - Diffuse Double Layer
Ligand:	Pb<2+> - lead
Site Type:	»Fe(s1)-OH
Equation:	»Fe(s1)-OH + Pb<2+> ⇔ »Fe(s1)-O-Pb<1+> + H<1+>
LogK:	7.2 LogK°_I=0 (Conversion to I = 0): 7.20
Experiment:	Batch Sorption Experiments
Ionic Strength:	0.0 mol/L
Temperature:	298.15 K
pH Range:	3 - 6
Fit Method:	FITEQL
Comment:	3-site model (third higher affinity site); Pb conc. of 9.86 µmol/kg, Fe concentration of 1.09 mmol/kg; no convergence of this value so it was fixed to achieve consistency between results
