Electrochemical Detection of Furaltadone Antibiotic Drug by the Rare Earth Metal Tungstate Decorated Screen Printed Carbon Electrode

Furaltadone (FLD) is an antibiotic drug that widely treated for coccidiosis, intestinal infection, and turkey blackhead. Moreover, excessive use of FLD may have some negative consequences humans domestic animals. Therefore, practical, sensitive, selective, facile detection still needed. In this exploration, a Eu2(WO4)3-nanoparticles-modified screen-printed carbon electrode was developed the low-level FLD. Hydrothermal techniques were used effectively to prepare Eu2(WO4)3 complex. Scanning electron microscopy X-ray diffraction investigations confirm Eu2(WO4)3. The results revealed well formed, crystalline, uniformly distributed. Furthermore, electrochemical behavior SPCE/Eu2(WO4) examined by differential pulse voltammetry cyclic studies. demonstrated improved electrocatalytic activity in with limit 97 µM (S/N = 3), linear range 10 nM 300 µM, sensitivity 2.1335 µA µM−1 cm−2. detected presence 500-fold excess concentrations other interfering pollutant ions. practical feasibility tested on different medicines showed adequate recovery. shows appreciable repeatability, high stability, reproducibility.
