Interactions between pyridine-2,5dicarboxylic acid and Zn(II), Ni(II), Pb(II), Cd(II), and Cu(II) were characterized in aqueous solutions (20 • C; I = 0.4 (KNO 3 )) by means of d.c.-polarography, spectrophotometry, and 1 H NMR spectroscopy. Polarography was used to determine the concentration of fre

The oxidative matrix polymerization of pyrrole (Py) by Fe(III), Cu(II), Ni(II), Co(II), and Zn(II) in the presence of polyacrylic acid (PAA) was studied and water-soluble products along with insoluble products were obtained. The metal (Me) content of the insoluble part was determined by using atomic
## Abstract Interactions between pyridine‐2,6‐dicarboxylic acid and 4‐hydroxypyridine‐2,6‐dicarboxylic acid with Cu(II), Pb(II), and Cd(II) ions were characterized in aqueous solutions (20°C; I = 0.4 (KNO~3~)) by means of dc‐polarography. In solutions with excess of ligand, Cu(II), Pb(II), and Cd(I
