SCM Type: CDM - (CD-)MUSIC
Ligand: Pb<2+> - lead
Site Type: »Fe-singly
Equation: 2 »Fe-singly-OH<0.5-> + Pb<2+> + H2O  ⇔  (»Fe-singly-OH)2-Pb(OH) + H<1+>
LogK: 2.08         LogK2.31 nm−2 (SSD-normalized):   1.79
Experiment: Batch Sorption Experiments
Ionic Strength: NaNO3
Temperature: 298.0 K
Solid/Liquid Ratio: 0.2 g/L
pH Range: 3-8
Ligand Concentration Range: 1E-6 and 1E-5 mol/L
