Surface Complex Formation Data:

Mineral: Goethite
Reference: NFHPL17
SCM Type: ES - Extended Stern
Ligand: Sr<2+> - strontium
Site Type: »Fe-triply
Equation: »Fe-triply-O<0.5-> + Sr<2+>  ⇔  »Fe-triply-O-Sr<1.5+>
LogK: 4.89        LogK°I=0 (Conversion to I = 0):   5.07         LogK2.31 nm−2 (SSD-normalized):   4.89
Experiment: Batch Sorption Experiments
