Voltammetric determination of zinc in aqueous solutions of
poly-n-vinylpyrrolidone
Abstract
The process of zinc electrodissolution from the graphite electrode surface
in absence and in presence of water-soluble polymer poly-N-vinylpirrolidone was
studied by means of stripping voltammetry. It was not found a significant
influence of the polymer to kinetics of the electrode process. The dependencies
of anodic peaks values from Zn(II) concentration were linear. The possibility
of Zn(II) determination in the absence and in the presence of 1 % polymer in model solutions was shown.
