Reference: HWCS15
SCM Type: DDL - Diffuse Double Layer
Ligand: Cd<2+> - cadmium
Site Type: »X-OH
Equation: 2 »X-OH + Cd<2+> + H2O  ⇔  (»X-O)2-Cd(OH)<1-> + 3 H<1+>
LogK: -8.11        LogK°I=0 (Conversion to I = 0):   -8.07         LogK2.31 nm−2 (SSD-normalized):   0.60
Experiment: Batch Sorption Experiments
Ionic Strength: 0.01 mol/L NaClO4
Temperature: 293.0 K
Solid/Liquid Ratio: 1.2 g/L
pH Range: 2-10
Fit Method: FITEQL
Comment: 2 identical equations 2 »X-OH + UO2<2+> + H2O = (»X-O)2-UO2(OH)<1-> + 3 H<1+> with different logK values in the article; it is assumed that the first equation should be written with Cd<2+> (see table 5 in the article)
