Abstract
The escalating environmental contamination with furaltadone (FLT), a veterinary antibiotic with established mutagenic and carcinogenic properties, necessitates the development of efficient detection systems to monitor its prevalence in ecosystems. In response to this urgent need, this study introduces an innovative electrochemical sensor fabricated with praseodymium molybdates Pr2(MoO4)3 decorated glassy carbon electrode (GCE) for the sensitive and precise detection of FLT in environmental samples. Leveraging a hydrothermal approach for synthesizing Pr2(MoO4)3, we comprehensively characterized the resultant nanocomposites using various advanced techniques including XRD, Raman, FT-IR, TEM, and EIS studies. The sensor demonstrated remarkable proficiency in FLT detection, exhibiting extensive linear ranges (0.001–616.05 µM) and a lower detection limit of 0.63 nM through the employment of electrochemical methods like cyclic voltammetry (CV) and differential pulse voltammetry (DPV). Notably, it successfully analyzed water samples, showcasing promising potential as a realistic material for developing highly efficient FLT sensors for environmental applications, thus representing a significant stride towards safeguarding human health and preserving the biosphere.
