RES³T - Rossendorf Expert System for Surface and Sorption Thermodynamics

Show Detailed Complexation Query Results


Surface Complex Formation Data:

Mineral: Kaolinite
Reference: HZBRM97
SCM Type: TL - Triple Layer
Ligand: PO4<3-> - phosphate
Site Type: »Si-OH
Equation: »Si-OH + PO4<3-> + H<1+>  ⇔  »Si-OH2-PO4<2->
LogK: 18.6        LogK°I=0 (Conversion to I = 0):   19.05
Experiment: Batch Sorption Experiments
Ionic Strength: 0.01 mol/L KCl
Fit Method: FITEQL
Comment: logK for background electrolyt for Na+ onto >>SiOH=-3,5 from [R82] (SCM type probably not TL!); also log K in 0.1M KCl: 19.12, in 1M KCl: 20.85; outer sphere complex; bad fit >20 for all ionic strengths
