Use of Monovalent Copper for Sensitive Detection of Methyl Derivatives of Xanthine
Navrátil, R. ; Motlova, D. ; Jelen, F. ; Trnková, L.
This work is concerned with the electroanalysis of xanthine (Xan) and its methylated derivatives (1-, 3-, 7-, and 9-mXan) on a pencil graphite electrode in the presence of copper ions. The main idea of using copper consists in the in situ formation of the complex Cu(I)-mXan on the electrode surface and improvement of oxidative signals of the corresponding mXan during the detection. Linear sweep voltammetry (LSV) in connection with adsorption stripping techniques was used for the determination of mXan. To enhance the oxidation signals the elimination voltammetric procedure (EVP) was applied.
