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.
