Show Detailed Complexation Query Results


Surface Complex Formation Data:

Mineral: Montmorillonite
Reference: BB97b
SCM Type: NE - Non-electrostatic
Ligand: Mn<2+> - manganese(II)
Site Type: »X(s)-OH
Equation: »X(s)-OH + Mn<2+>  ⇔  »X(s)-O-Mn<1+> + H<1+>
LogK: -0.2 ± 0.15         LogK°I=0 (Conversion to I = 0):   0.12
Experiment: Batch Sorption Experiments
Ionic Strength: 0.1 mol/L NaClO4
Solid/Liquid Ratio: 6.4 g/L
pH Range: 4-11.5
Fit Method: MINSORB
Comment: Na-montmorillonite, MINSORB code (2-site protolysis); \"inactive\" sorption edge; fixed parameters: Zn sorption parameters (logK on strong sites 1.6, on weak sites -2.7) and Zn inventory (1E-3mol/kg); deduced from experimental data having relatively large uncertainties; only an estimate!
