In this work, a new electrochemical sensor based on pencil graphite with interesting features, such as low cost (US$ 0.01 per electrode), ease manufacture, and portability was developed. The sensor showed an adequate manufacturing reproducibility with RSD <5.3 %. Under this electrochemical platform, ciprofloxacin underwent an irreversible oxidation process at 1.03 V, characterized by the diffusion...
In this paper, bare glassy carbon electrode (GCE), multi‐walled carbon nanotubes (MWCNT/GCE) and reduced graphene oxide (RGO/GCE) were to verify the ciprofloxacin oxidation process. The RGO/GCE electrode provided a 9‐fold increase in the analytical signal and a potential displacement of 50 mV. A method using flow injection analysis with amperometric detection has been developed for simple and fast...
