Surface Complex Formation Data:

Mineral: amorphous Al(OH)₃
Reference: ML93b
SCM Type: TL - Triple Layer
Ligand: SO4<2-> - sulfate
Site Type: »Al-OH
Equation: 11 »Al-OH + SO4<2-> + H<1+>  ⇔  (»Al-OH)10-Al-SO4<1-> + H2O
LogK: 9.0        LogK°I=0 (Conversion to I = 0):   9.39         LogK2.31 nm−2 (SSD-normalized):   -6.24
Experiment: Batch Sorption Experiments
Ionic Strength: 0.04 mol/L KNO3
Fit Method: MINTEQA2
Comment: AlOH site coverage of 11 sites per adsorbed H4SiO4 was required to model the H4SiO4 adsorption in suspensions containing different amounts of Al(OH)3; log determined by fitting the results of TLM computation to the experimental data for pure Al(OH)3
