Surface Complex Formation Data:

Mineral: Alumina
Reference: ZS94
SCM Type: TL - Triple Layer
Ligand: Cd<2+> - cadmium
Site Type: »Al-OH
Equation: »Al-OH + Cd<2+>  ⇔  »Al-O-Cd<1+> + H<1+>
LogK: -2.7         LogK2.31 nm−2 (SSD-normalized):  
Experiment: Batch Sorption Experiments
Ionic Strength: NaClO4
Solid/Liquid Ratio: 6.0 g/L
Fit Method: FITEQL
Comment: fit to Cd adsorption data on corundum-NaCl [H84] !; not clear whether corundum or alumina; based on pK of [H71] with pK1=5.7 and pK2=11.5 (but there other values); applied on Cd sorption onto montmorillonite and beidellite
