Surface Complex Formation Data:

Mineral: Alumina
Reference: RK11
SCM Type: TL - Triple Layer
Ligand: CO3<2-> - carbonate
Site Type: »Al-OH
Equation: 2 »Al-OH + CO3<2-> + 2 H<1+>  ⇔  (»Al-OH2<1+>)2-CO3<2->
LogK: 25.3         LogK2.31 nm−2 (SSD-normalized):   22.09
Experiment: Batch Sorption Experiments
Ionic Strength: NaNO3
Solid/Liquid Ratio: 5.0 g/L
pH Range: 4 - 10
Fit Method: FITEQL
Comment: ~2.5 % pCO2; median log K; 0.01 and 0.1 M NaNO3; chromate surface species: »AlOH2<1+>-HCrO4<1-> with best log K at 0.1 and 0.01 M NaNO3; also log K values for the species (»AlOH2<1+>)(»AlOH)-HCO3<1-> and (»AlOH2)(»AlOH)-HCO3 they resulted in overflow errors in FITEQL
