RES³T - Rossendorf Expert System for Surface and Sorption Thermodynamics

Show Detailed Complexation Query Results


Surface Complex Formation Data:

Mineral: Illite
Reference: EPH13
SCM Type: NE - Non-electrostatic
Ligand: Nb(OH)5<0> - niobium(V) hydroxyde
Site Type: »X(w)-OH
Equation: »X(w)-OH + Nb(OH)5<0>  ⇔  »X(w)-O-Nb(OH)4 + H2O
LogK: 1.0
Experiment: Batch Sorption Experiments
Ionic Strength: ground water
Temperature: 298.15 K
Solid/Liquid Ratio: 1.0 g/L
pH Range: 6 - 11
Ligand Concentration Range: 1E-8 mol/L
Fit Method: PHREEQC
Comment: The best fit from OLSR was applied to other waters (Figures Nb-10-12). However for the other waters the fitting did not succeed. Since the speciation in other waters is similar and the modeling results are the same as for OLSR, the other modeling results are not presented.
