“…Glassy carbon electrode is used very commonly because of its excellent mechanical and electrical properties, impermeability to gases, and extremely low porosity. 12) The literature survey revealed that no attempts Vol. 128 (2008) have been made to study the voltammetric behavior of Repag as an oxidation process and thus in continuation to our previous work, 13 16) the aim of this study is to establish and to optimize the experimental conditions for the determination of Repag in pure form, tablets, and serum by using cyclic voltammetry and diŠerential pulse voltammetry (DPV) techniques.…”

The electrochemical oxidation of repaglinide has been carried out in Britton-Robinson buŠer at carbon paste and glassy carbon electrodes. Repaglinide exhibits a well-deˆned irreversible oxidation peak over the entire pH range (2 11). DiŠerential pulse voltammetry was used to determine repaglinide in pure form. The peak current varied linearly in the following ranges: 8.0×10 -7  3.2×10-6 M and 4.0×10 -7  4.0×10 -6 M in case of carbon paste electrode and glassy carbon electrode, respectively. In case of carbon paste electrode the limits of detection (LOD) and quantiˆcation (LOQ) were 1.348×10 -7 M and 4.494×10 -7 M, respectively. For glassy carbon electrode the LOD and LOQ were 1.062×10 -7 M and 3.54×10 -7 M, respectively. The percentage recoveries were found in the following ranges: 99.09 100.07％ and 99.0 100.50％ for carbon paste electrode and glassy carbon electrode, respectively. The relative standard deviations were found in the following ranges: 0.636 1.395％ and 0.431 1.104％ in case of carbon paste electrode and glassy carbon electrode, respectively. DiŠerential pulse voltammetry was successfully applied for the determination of repaglinide in tablets and human serum.

In its conducting form, carbon has proven to be a versatile, robust and high performing electrode material in areas such as energy conversion, energy storage and even medical bionics. In our laboratories we have been interested in the fabrication and utilization of nanostructured electrodes based on more recently discovered forms of carbon. These include carbon nanotubes and graphene.

“…In addition, these electrodes offer the ability to perform such analytical determinations, which mercury or other electrodes are not always possible to do. It has been very popular because of its excellent electrical and mechanical properties, a wide potential range, extreme chemical inertness and relatively reproducible performance [10,16,17].…”
