Show Detailed Complexation Query Results


Surface Complex Formation Data:

Mineral: Alumina
Reference: KRKTM11
SCM Type: CC - Constant Capacitance
Ligand: TcO<2+> - technetium(IV)
Site Type: »Al-OH
Equation: »Al-OH + TcO<2+> + H2O  ⇔  »Al-O-TcO(OH) + 2 H<1+>
LogK: -1.01        LogK°I=0 (Conversion to I = 0):   -0.80         LogK2.31 nm−2 (SSD-normalized):   0.20
Experiment: Batch Sorption Experiments
Ionic Strength: 0.1 mol/L NaClO4
Solid/Liquid Ratio: 5.0 g/L
pH Range: 3-10
Ligand Concentration Range: 1E-12 mol/L
Fit Method: FITEQL
Comment: wrong equation in the article: »Al-OH + TcO<2+> + H2O = »Al-O-TcO(OH); reducing conditions simulated with [Sn(II)] = 1E-6 M
