Surface Complex Formation Data:

Mineral: Goethite
Reference: NFHPL17
SCM Type: CDM - (CD-)MUSIC
Ligand: Sr<2+> - strontium
Site Type: »Fe-singly
Equation: 2 »Fe-singly-OH<0.5-> + Sr<2+> + Cl<1->  ⇔  (»Fe-singly-OH)2-SrCl
LogK: 5.36        LogK°I=0 (Conversion to I = 0):   5.58         LogK2.31 nm−2 (SSD-normalized):   5.51
Experiment: Batch Sorption Experiments
