RES³T - Rossendorf Expert System for Surface and Sorption Thermodynamics

Show Detailed Complexation Query Results


Surface Complex Formation Data:

Mineral: Ferrihydrite
Reference: D78
SCM Type: TL - Triple Layer
Ligand: sal<2-> - salicylate
Site Type: »Fe-OH
Equation: »Fe-OH + sal<2-> + 2 H<1+>  ⇔  »Fe-OH2-salH
LogK: -24.1        LogK°I=0 (Conversion to I = 0):   -23.46         LogK2.31 nm−2 (SSD-normalized):   -23.16
Experiment: Potentiometric Titration
Ionic Strength: 0.1 mol/L NaNO3
Fit Method: graphic extrapolation
Comment: adsorbing species H(sal)-, better fit for >1E-4 M salicylic acid by assuming that each salicylic acid molecule occupies 16 surface sites !
