RES³T - Rossendorf Expert System for Surface and Sorption Thermodynamics

Show Detailed Complexation Query Results


Surface Complex Formation Data:

Mineral: Goethite
Reference: RL98
SCM Type: TL - Triple Layer
Ligand: Cu<2+> - copper
Site Type: »Fe(w)-OH
Equation: »Fe(w)-OH + Cu<2+> + H2O  ⇔  »Fe(w)-O-Cu(OH) + 2 H<1+>
LogK: -7.168        LogK°I=0 (Conversion to I = 0):   -7.17         LogK2.31 nm−2 (SSD-normalized):   -2.40
Experiment: Sorption Isotherms
Ionic Strength: 0.0 mol/L NaClO4
pH Range: 6,07, 5,07, 4,07
Fit Method: FITEQL
Comment: I = 0.01 and 0.1 M; modified TLM: indifferent electrolyte-surface interactions, electrolyte ions accumulate to screen surface charge, but do not form complexes with surface sites; fit with assumption of =FeOCu+ and =FeOCuOH; WSOS/DF=15.1
