Several multi-dentate podand ligands, including 3 to 5 nitrogen atoms, were synthesized in an attempt to produce ligands useful for removing metal ions from water-based solutions.  The ligands were created from the common starting materials diethylenetriamine (N3), triethylenetetraamine (N4), and tetraethylenepentaamine (N5) combined with octanal, decanal, and dodecyl aldehyde using Schiff’s base condensations.  The purpose of this project is to identify inexpensive, easy-to-synthesize ligands which can be used for water remediation.<br/>
