Abstract
The complex formation of poly(N-vinyl imidazole) (PVIm) with various metal ions was studied. UV-vis spectroscopy was employed to study the interaction of PVIm and metal ions in aqueous solution. Formation constants of PVIm-me tal complexes were calculated by applying a "mole ratio" method. The stoich iometric ratios between polymer and metal ions were found to be 4. The stab ility constants for the complexes of PVIm with bivalent transition metal io ns were in agreement with the Irving-William series. The biggest formation constant was found for the PVIm-Cu2+ complex system.
