RES³T - Rossendorf Expert System for Surface and Sorption Thermodynamics

Show Detailed Complexation Query Results


Surface Complex Formation Data:

Mineral: Kaolinite
Reference: TS96
SCM Type: DDL - Diffuse Double Layer
Ligand: UO2<2+> - uranyl(VI)
Site Type: »Al-OH
Equation: »Al-OH + UO2<2+> + H2O  ⇔  »Al-O-UO2(OH) + 2 H<1+>
LogK: -4.74        LogK°I=0 (Conversion to I = 0):   -4.74         LogK2.31 nm−2 (SSD-normalized):   -6.13
Experiment: Batch Sorption Experiments
Ionic Strength: 0.0 mol/L NaNO3
Solid/Liquid Ratio: 4.0 g/L
pH Range: 3-7.5
Ligand Concentration Range: 1E-6 mol/L
Fit Method: FITEQL
Comment: experimental data from [PSDW92], experiments were performed at IS = 0.1 M NaNO3, values were corrected for IS = 0; sorption behavior is probably a combination of ion exchange at intercrystalline sites and surface complexation along edge sites
