General description

Ethylenediaminetetraacetic acid (EDTA, N,N,N′,N′-ethylenediaminetetraacetic acid) is a chelating agent. It forms complexes with rare earth metal ions and the stability constants of these complexes have been evaluated. Hydroxyl radicals generated pulse radiolytically in N2O- and N2O-O2-saturated solutions reacts with EDTA. Absorption spectrum of this reaction was recorded and maxima was observed at 275 and 480nm. EDTA is an excellent ligand for Cd(II) and forms stable Cd-EDTA complexes. 113Cd NMR studies of Cd-EDTA complexes have been reported.

Application

Ethylenediaminetetraacetic acid (EDTA) may be employed in a microtiter plate assay. In this assay, interaction between EDTA or lactoferrin and nisin, lysozyme, or monolaurin against Listeria monocytogenes, Escherichia coli, Salmonella enteritidis, and Pseudomonas fluorescens strains was investigated.[1]
