Show Detailed Complexation Query Results


Surface Complex Formation Data:

Mineral: Goethite
Reference: RL98
SCM Type: DDL - Diffuse Double Layer
Ligand: Cu<2+> - copper
Site Type: »Fe(s)-OH
Equation: »Fe(s)-OH + Cu<2+>  ⇔  »Fe(s)-O-Cu<1+> + H<1+>
LogK: 4.304        LogK°I=0 (Conversion to I = 0):   4.30         LogK2.31 nm−2 (SSD-normalized):   7.43
Experiment: Sorption Isotherms
Ionic Strength: 0.0 mol/L NaClO4
pH Range: 6.07, 5.07, 4.07
Fit Method: FITEQL
Comment: I = 0.01and 0.1 M; experimental data can be replicated well by assuming three binding sites, data given here are valid for class 2 (second site class typically repesented 0.2-0.5% of the total site concentration); fit with assumption of =FeOCu+ and =FeOCuOH; WSOS/DF=6.2
