Show Detailed Complexation Query Results


Surface Complex Formation Data:

Mineral: Ferrihydrite
Reference: K97d
SCM Type: DDL - Diffuse Double Layer
Ligand: Cu<2+> - copper
Site Type: »Fe(w)-OH
Equation: »Fe(w)-OH + Cu<2+>  ⇔  »Fe(w)-O-Cu<1+> + H<1+>
LogK: 1.5         LogK2.31 nm−2 (SSD-normalized):   3.23
Experiment: Batch Sorption Experiments
Ionic Strength:
Temperature: 291.15 K
pH Range: 6.5-7.5
Ligand Concentration Range: 1E-4.169 mol/L
Fit Method:
Comment: at higher pH model breaks down because of hydrolysis, assuming single-site model (only weak sites), temperature 18+-0.5°C
