This study is aimed at the determination of a new pollutant, fluoroquinolones antibiotics (FQs). Taking ciprofloxacin (CIP) as the research representative, rutin polymer film-modified sensor polyrutin modified glass carbon electrode (PRT/GCE) was prepared by electropolymerization, and a new analytical method for the determination of FQs was established, which is environmentally friendly, simple, efficient, and economical. The topography, elemental composition, and electrochemical behavior of the sensor were investigated using scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), electrochemical impedance spectroscopy (EIS), and cyclic voltammetry (CV). The results showed that the linear range of the PRT/GCE sensor used for CIP was 0.8–50 μM, the detection limit was 0.050 μM, and the recovery rate was 94.9%–104%. In addition, when it was used to detect norfloxacin (NOR), enrofloxacin (ENR), pefloxacin (PEF), and rofloxacin (FLE) in FQs, the sensor similarly exhibited a broad linear range; its corresponding detection limits were 0.078, 0.16, 0.088, and 0.12 μM, respectively. The PRT/GCE sensor had a high active area, good catalytic performance for FQs, simple preparation, stable performance, and reusability. It has potential application value for routine determination of fluoroquinolones in real water.

Here, we report a simple one-step preparation of polyrutin/silver nanoparticles (AgNPs) on the glassy carbon electrode (GCE) surface using an electrochemical deposition/polymerization technique. As prepared polyrutin/AgNPs/GCE has been characterized by different techniques such as SEM with elemental morphing, TEM with EDAX , XRD , ATR-IR to confirm the materials formation. Further, electrochemical behavior of the polyrutin/AgNPs/GCE was tested by cyclic voltammetry , EIS and differential pulse voltammetric techniques. As fabricated polyrutin/AgNPs/GCE was used for simultaneous detection of Pb(II) and Cd(II)ions using anodic stripping voltammetric techniques and stripping analysis of Pb(II) and Cd(II)ions analytical parameters like pH, preconcentration time were studied. The polyrutin/AgNPs/GCE has showed a linear concentration range from 29 nM to 140 nM and 57–203 nM with detection limit of 3 nM and 10 nM for Pb(II) Cd(II)ions respectively. Further, the modified electrode was tested towards detection of these heavy metal ions in different environmental samples and the found excellent recovery results were further correlated with ICP-MS results.
