Abstract:
In this article, the equimolar mixtures of acrylamide (AAm) and quercetin or
glycine in aqueous solution at different pH, and after heating (100 °C for 60 min)
have been studied. (Bare) pencil graphite electrode (PGE) in combination with
square wave voltammetry were applied to the qualitative identification of the
products. An interaction of AAm and quercetin at pH 2.0 resulted in the increase
of reduction current at +128 mV, and an additional shift to +140 mV before and
after heat treatment, respectively. PGE gave rise to only response for heat-treated
AA/glycine mixture at pH 2.0, showing a higher oxidation current at positive
potential and a higher reduction current at negative potential. In neutral media,
two oxidation peaks were observed for heated AAm/glycine mixture. Theoretical
considerations have been proposed.
