Reference: NFHPL17
SCM Type: ES - Extended Stern
Ligand: Sr<2+> - strontium
Site Type: »Fe-singly
Equation: 2 »Fe-singly-OH<0.5-> + Sr<2+>  ⇔  (»Fe-singly-OH)2-Sr<1+>
LogK: 0.96        LogK°I=0 (Conversion to I = 0):   1.14         LogK2.31 nm−2 (SSD-normalized):   1.11
Experiment: Batch Sorption Experiments
