RES³T - Rossendorf Expert System for Surface and Sorption Thermodynamics

Show Detailed Complexation Query Results


Surface Complex Formation Data:

Mineral: Kaolinite
Reference: EPH13
SCM Type: NE - Non-electrostatic
Ligand: Th<4+> - thorium
Site Type: »X(s)-OH
Equation: »X(s)-OH + Th<4+> + CO3<2-> + 2 H2O  ⇔  »X(s)-O-Th(OH)2(CO3)<1-> + 3 H<1+>
LogK: 5.1
Experiment: Batch Sorption Experiments
Ionic Strength: ground water
Solid/Liquid Ratio: 0.5 g/L
pH Range: 6 - 11
Ligand Concentration Range: 1E-10 mol/L
Fit Method: PHREEQC
Comment: Modeling first applied to OLSR (saline ground water); parameters and surface species of best fit from OLSR were applied to other waters (ALLMR, OLBA, OLGA); for other waters it was necessary to fit thorium hydroxo carbonato species
