Abstract
In this study, Pers., which is an important holoparasite plant, was used for green synthesis of reduced graphene oxide silver nanocomposites (rGO-AgNCs). The obtained rGO-AgNCs were characterizated using UV–Vis spectroscopy, Fourier transformation infrared spectroscopy (FT-IR), X-Ray diffractiometer (XRD), Scanning electron microscope (SEM), Transmission electron microscope (TEM), and X-Ray photoelectron spectroscopy (XPS). The synthesized rGO-AgNCs structure were used to modify carbon paste electrode (rGO-AgNCs@CPE) for electrochemical determination of metronidazole (MNZ). It was observed that the obtained rGO-AgNCs@CPE showed higher sensitivity in MNZ determination than the unmodified CPE, and DPV measurements showed a low detection limit of 0.039 μM over a linear concentration range of 5–300 μM. Real sample analysis of the proposed sensor shows that it responds well in MNZ analysis of human urine.
期刊介绍：
The Microchemical Journal is a peer reviewed journal devoted to all aspects and phases of analytical chemistry and chemical analysis. The Microchemical Journal publishes articles which are at the forefront of modern analytical chemistry and cover innovations in the techniques to the finest possible limits. This includes fundamental aspects, instrumentation, new developments, innovative and novel methods and applications including environmental and clinical field.
Traditional classical analytical methods such as spectrophotometry and titrimetry as well as established instrumentation methods such as flame and graphite furnace atomic absorption spectrometry, gas chromatography, and modified glassy or carbon electrode electrochemical methods will be considered, provided they show significant improvements and novelty compared to the established methods.
