Abstract: The N,N'-di(2-hydroxybenzyl)ethylenediamine-N,N'-diacetic acid (HBED) represents a pplydonor ligand with phenolic functional group, which is suitable for chelation with M(III). The Potentiometrie measurements, UV spectrophotometry, and  1H NMR spectroscopy were used for the study of acid-base properties. The study of complex formation with rare earth elements was performed by Potentiometrie method and paper electrophoresis. The stability constants of complexes of ML type, as well as the hydrogen complexes of MH2L and MHL type at Ic(KNO3) = 0.1 mol dm-3 and T = 293.2 К were evaluated from the neutralization curves.
