Abstract:
Aqueous solutions containing polyvinylpyrrolidone and zinc and silver nitrates are studied by IR spectroscopy. It is shown that introduction of zinc and silver nitrates into polyvinylpyrrolidone solutions leads to a shift of the polymer absorption bands to lower wavenumbers. The results obtained indicate the possibility of formation of complexes consisting of polymer molecules and metal ions.
Keywords:
IR spectroscopy, absorption spectrum, polyvinylpyrrolidone, metal ions.
