Show Detailed Complexation Query Results


Surface Complex Formation Data:

Mineral: Goethite
Reference: RL98
SCM Type: TL - Triple Layer
Ligand: Cu<2+> - copper
Site Type: »Fe-OH
Equation: »Fe-OH + Cu<2+> + ClO4<1->  ⇔  »Fe-O-CuClO4 + H<1+>
LogK: 2.552        LogK°I=0 (Conversion to I = 0):   2.55         LogK2.31 nm−2 (SSD-normalized):   7.58
Experiment: Sorption Isotherms
Ionic Strength: 0.0 mol/L NaClO4
pH Range: 6.07, 5.07, 4.07
Fit Method: FITEQL
Comment: I = 0.01 and 0.1 M; bad fit with WSOS/DF=136.9; fit with only assumption of =FeOCu+ complex; single class of copper binding sites yielded poor results
