Show Detailed Complexation Query Results

Surface Complex Formation Data:

Mineral:	Ferrihydrite
Reference:	BL81a
SCM Type:	DDL - Diffuse Double Layer
Ligand:	Cd<2+> - cadmium
Site Type:	»Fe-OH
Equation:	»Fe-OH + Cd<2+> ⇔ »Fe-O-Cd<1+> + H<1+>
LogK:	-3.4 LogK°_I=0 (Conversion to I = 0): -3.08
Experiment:	Batch Sorption Experiments
