Abstrakt:
A simple indirect method for acrylamide determination using a carbon paste
electrode (CPE) modified with powdered ruthenium dioxide is described in the
study. The voltammetric response of RuO2/CPE in a 1.0 M LiCl supporting
electrolyte resulted in the reduction current at a potential of 1.03 V vs. Ag/AgCl/
3.0 M KCl due to the formation of unspecified Ru-Cl species. The addition of
acrylamide decreased the reduction current at 1.03 V, giving rise to a linear
response in the concentration range from 0.25 μM to 1.5 μM with a limit
of detection found to be 0.94 μM. The method developed was successfully
applied to analyse potato crisps sample with a recovery rate of 97.9 %.
