Abstract:
In this paper, electrochemical and electroanalytical characterization of caffeine
has been carried out, for the first time, with unmodified carbon paste electrode
and in combination with cyclic voltammetry and square-wave voltammetry as the
measuring techniques of choice. After defining the proper conditions for the
electrode oxidation in highly acidic media and setting the key experimental
parameters accordingly, a simple method was subsequently tested on model
analyses of real samples (energy and Cola drinks).
