Lanthanide (Ln

Bifunctional chelate EDTA-bis amide (N,N'-bis (tyramide)ethylenediamine-N,N'-diacetic acid) that has ability to mimic natural amino acids was synthesized and analyzed by various spectroscopic techniques. The physicochemical studies were performed to calculate the various thermodynamic and kinetic parameters for the synthesized poly-amino carboxylate ligand. The two protonation constant (pka's = 3.460 and 6.722) of the prepared ligand and stability constants (log K
