Abstract

Importance in the precise determination of Furazolidone (FZD) on biological, food, and water samples were established for regulating health and nutrition, diagnosis/treatment, pharmacological research, and food/drug quality monitoring. Thus, the sensitive and accurate determination of FZD is necessary. Here, we construct facile and low-cost Metal Titanate (MTiOx, M = Mn, Fe, Cu) as an electrode modifier via a different one-step synthesis method. By the virtue of unique properties, MnTiO3 has been successfully employed in the electrochemical evaluation of FZD such as high active surface area (0.1252 cm2) and high electron transfer kinetics with low charge transfer resistance (Rct = 374.65 Ω) with good electro-catalytic kinetic parameters. In this regard, MnTiO3 is employed in the electrochemical evaluation of FZD through cyclic voltammetry (CV) and Differential Pulse Voltammetry (DPV) techniques. The proposed MnTiO3/GCE sensor shows exquisite electrochemical characteristics including a wide linear range (0.05 to 1101.6 µM), nanomolar detection limit (4.05 nM), and encouraging sensitivity (68.77 µA µM−1 cm−2). Moreover, it also exemplifies exquisite selectivity, repeatability, reproducibility, and storage stability therefore; MnTiO3 is employed in the practical feasibility analysis in various real samples, which shows excellent recovery results.
