| Description | Electroanalysis of xanthine (Xan) and its three methylated derivatives (1-, 3-, and 7-mXan) on a pencil graphite electrode (PeGE) in the presence of copper ions is presented. For a sensitive detection of their oxidation signals represented not only by copper complexes but also by the corresponding methyl-substituted Xan the combination of adsorptive stripping and elimination techniques was used. It was found that the position of methyl group on the xanthine ring is responsible for both the potential and peak height of all methylxanthines. |
