RES³T - Rossendorf Expert System for Surface and Sorption Thermodynamics

Show Detailed Complexation Query Results


Surface Complex Formation Data:

Mineral: Gibbsite
Reference: DMBC97
SCM Type: NE - Non-electrostatic
Ligand: NpO2<1+> - neptunyl(V)
Site Type: »Al-OH
Equation: »Al-OH + NpO2<1+>  ⇔  »Al-O-NpO2 + H<1+>
LogK: -3.41        LogK°I=0 (Conversion to I = 0):   -3.41         LogK2.31 nm−2 (SSD-normalized):   -4.80
Experiment: Batch Sorption Experiments
Ionic Strength: 0.01 mol/L NaClO4
Temperature: 298.0 K
pH Range: 4.5-9
Ligand Concentration Range: 1E-13 - 1E-14 mol/L
Fit Method: EQIL-DISSOL
Comment: log K = -3.44 for I = 0.1 M; solid concentration 10 and 50 g/L; no influence of ionic strength, presence of small amounts of carbonate (<1E-4 M) induces no change in sorption
