Abstract:
Schiff base readily form complex with metal ions and the resultant complexes especially from transition metals were extensively used in many fields of human endeavor including antimicrobial therapy. However, the potentials of Lanthanide-Schiff base complexes as an antimicrobial agent have not been adequately studied. This study aims to synthesize and determine the antimicrobial activity of Bis-salicylaldehyde ethylenediamine Schiff Base and its Lanthanoids (III) Complexes.

Stability of Fe3+ complexes in nutrient solution, rate of metal exchange with Ca, and rate of Fe extraction by the free ligand were monitored for rhizoferrin
