Show Detailed Complexation Query Results


Surface Complex Formation Data:

Mineral: Ferrihydrite
Reference: HPL88
SCM Type: TL - Triple Layer
Ligand: SeO4<2-> - selenate
Site Type: »Fe-OH
Equation: »Fe-OH + SeO4<2-> + H<1+>  ⇔  »Fe-SeO4<1-> + H2O
LogK: 7.7        LogK°I=0 (Conversion to I = 0):   7.70         LogK2.31 nm−2 (SSD-normalized):   8.64
Experiment: Batch Sorption Experiments
Ionic Strength: 0.0 mol/L NaNO3
Solid/Liquid Ratio: 0.09 g/L
pH Range: 4-9
Ligand Concentration Range: 1E-4 mol/L
Fit Method: graphic extrapolation
Comment: inner-spheric surface complex not suitable for the moddeling of SeO4<2-> onto ferrihydrite (HFO). Not to be used in combination with the outer-spheric sufrace complexes »Fe-OH2-SeO4<1-> and »Fe-OH2-HSeO4<->.
