RES³T - Rossendorf Expert System for Surface and Sorption Thermodynamics

Show Detailed Complexation Query Results


Surface Complex Formation Data:

Mineral: Montmorillonite
Reference: GSF98
SCM Type: TL - Triple Layer
Ligand: MoO4<2-> - molybdate
Site Type: »Al-OH
Equation: »Al-OH + H2MoO4  ⇔  »Al-OH2-MoO4<1-> + H<1+>
LogK: -0.92         LogK2.31 nm−2 (SSD-normalized):   -2.31
Experiment: Batch Sorption Experiments
Ionic Strength: NaCl
Temperature: 296.15 K
Fit Method: FITEQL
Comment: 23+-1°C; value for outer-sphere mechanism (no convergence for inner-sphere); ionic strength 0.01, 0.1, 1M NaCl; acceptable model fit only using an outer-sphere mechanism, in contradiction with the inner-sphere implied by the small ionic strength dependence of the adsorption data
