Show Detailed Complexation Query Results


Surface Complex Formation Data:

Mineral: Goethite
Reference: PB95
SCM Type: TL - Triple Layer
Ligand: NpO2<2+> - neptunyl(VI)
Site Type: »Fe-OH
Equation: »Fe-OH + NpO2<2+> + 3 CO3<2-> + H<1+>  ⇔  »Fe-OH2-NpO2(CO3)3<3->
LogK: 33.5        LogK°I=0 (Conversion to I = 0):   35.32         LogK2.31 nm−2 (SSD-normalized):   34.44
Experiment: Batch Sorption Experiments
Ionic Strength: 0.1 mol/L NaCl
