Abstract
Background:
Electrochemical oxidation mechanism and electrochemical determination of meloxicam
(M), an anti-artrithtis agent, were investigated by cyclic voltammetry and square wave adsorptive
stripping voltammetry, respectively.
</P><P>
Objective: In this study, we aimed to investigate the electrochemical redox mechanism and develop a
nano-sensor for sensitive, fast and selective analysis of meloxicam.
Methods:
In this study, the three-electrode system was used for all voltammetric measurements. Firstly,
the graphene content of GR/CPE sensor was changed in the range of 1.67% to 6.68%. Then, the surface
characterization of modified electrode was carried out by using Electrochemical Empedance Spectroscopy
and Surface Electron Microscopy methods. Some analytical parameters, such as pH, accumulation
potential and accumulation time were optimized and by using optimum parameters, calibration study
was established.
Results:
The GR/CPE with a graphene content of 3.33 % was found to have the best voltammetric signal
with a linear working range of 0.1–10 µM. The sensitivity of the quantitative voltammetric method
towards M is fairly good with an LOQ of 0.0088 μmol/L and LOD of 0.0026 µmol/L.
Conclusion:
The optimum pH, accumulation time and accumulation potential were found to be 2.0,
150s and 0.0 V, respectively. The height of the voltammetric signal obtained with the GR/CPE electrode
was stable with a 4.0 % deviation for a period of not shorter than 1 months.
