| Abstract | Interactions between pyridine-2,5- dicarboxylic acid and Zn(II), Ni(II), Pb(II), Cd(II), and Cu(II) were characterized in aqueous solutions (20 â—¦ C; I = 0.4 (KNO3)) by means of d.c.-polarography, spectrophotometry, and 1 H NMR spectroscopy. Po- larography was used to determine the concentration of free metal ions in the presence of 10-fold excess ligand in weakly alkaline solutions, and to determine stability constants for the Zn(II), Cd(II), and Cu(II) complexes with pyridine-2,5-dicarboxylic acid. 1 H NMR spectroscopy was used to further characterize complex formation.
