Electrochemical behavior of some purine derivatives on carbon based electrodes
Abstract: The electrochemical behaviour of three purine derivatives was investigated by cyclic voltammetry on different electrode materials: glassy carbon in native form and electrochemically activated, carbon paste electrode unmodified or modified with 1, 4-benzoquinone. The preliminary study obtained on solid electrodes was extended to graphite based planar screen-printed electrodes, unmodified and modified with multi-wall carbon nanotubes, or cobalt phthalocyanine. The influence of some experimental parameters (pH, scan rate, concentration and electrolytic medium) on the electrochemical behaviour of these alkaloids was also examined. The electrochemical oxidation of purine derivatives is an irreversible and diffusion controlled process, proved by the linear dependence between the peak potentials and the logarithm of scan rates and between the anodic peak current and the square root of scan rate.
