Sodium salts of iminodiacetic acid (IDA), ethylenediaminetetraacetic acid (EDTA), 1,2-propylenediaminetetraacetic acid (PDTA) and 1,2-diaminocyclohexanetetraacetic acid (DCTA) were prepared by modification of the literature methods and their i.r. and Raman spectra were studied.The results obtained by application of both techniques allowed a better characterization of these polydentate ligands.Raman spectroscopy was specially useful in elucidating structural aspects in compounds containing acetate groups.
