Show Detailed Complexation Query Results


Surface Complex Formation Data:

Mineral: Kaolinite
Reference: HZBRM97
SCM Type: TL - Triple Layer
Ligand: PO4<3-> - phosphate
Site Type: »Al-OH
Equation: »Al-OH + PO4<3-> + 2 H<1+>  ⇔  »Al-HPO4<1-> + H2O
LogK: 22.37        LogK°I=0 (Conversion to I = 0):   23.55         LogK2.31 nm−2 (SSD-normalized):   20.98
Experiment: Batch Sorption Experiments
Ionic Strength: 0.1 mol/L KCl
Fit Method: FITEQL
Comment: logK for background electrolyt for Na+ onto >>AlOH=-9.2 and for Cl- onto >>AlOH=7.90 from [JP82]; also log K in 1M KCl: 24.53; inner sphere complex; bad fit >20 for both ionic strengths
