Description:
The naturally occurring metal-chelating compounds known as siderophores may be useful in environmental applications but limited metal specificity data is available for this class of compounds. Correlations that predict ligand-metal affinity versus mtal ion charge density and hydrolysis behavior are applied to the case of the siderophore Desferrioxamine B (DFB). DFB-metal complex formation constants are better correlated to the first hydrolysis constant of the respective metal cations than to the ratio of charge to metal-ligand interatomic separation. Test cases of PbII, SnII and BiIII confirm this conclusion.
