Abstract: A study of chelate-forming ligand of the monoaminic type, i.e.DL-N-(2,3-dihydroxpropy)-N-carboxymethylaminoacetic acid is described. By using the methods of paper electrophoresis and potentiometric pH measurements in equil. systems contg. 2,2'2''-triaminotriethylamine, the formation of the chelate complexes with the tivalent lanthanide ions was studied. The formation of the complexes with the trivalent cations of Al, Sc, Y, In, Fe, and Lu was studied only by the method of paper electrophoresis. The complexon forms with the above ions ML and ML₂ chelates. The investigations were carried out under equal conditions, i.e. I = 0.10 M (KNO₃), t = 20°C.
