Abstract

This study reports a facile sonohydrolysis synthesis route to prepare the iron antimony oxide (FeSbO) nanoparticles for the trace level electrochemical sensing of fungicide carbendazim (CRBZ). As prepared FeSbO nanoparticles show a nano-cubes-like morphology with uniform distributions that crystallized in the tetragonal phase. The diffraction studies reveal that the FeSbO nanoparticles have high crystallinity and high purity. Furthermore, the other structural properties and morphology are characterized by XRD, Raman, XPS, HRTEM, and FESEM analysis. The electrochemical characterizations of FeSbO modified GCE towards the detection of CRBZ are performed by cyclic voltammetry and chronoamperometry techniques. The FeSbO/GCE exhibits a linear range from 0.01 µmol L to 64.3 µmol L, the sensitivity of 0.68 µA cm µM, and the LOD of 5.4 nmol L. Moreover, the FeSbO/GCE delivered high selectivity among the possibly interfering compounds. Also, our projected FeSbO/GCE electrode material shows good recoveries in apple juice and paddy water real samples.

摘要

本研究报告了一种简便的声水解合成路线，用于制备铁锑氧化物 (FeSbO) 纳米粒子，用于痕量水平的杀菌剂多菌灵 (CRBZ) 的电化学传感。所制备的 FeSbO 纳米粒子呈纳米立方体形，具有均匀的分布，结晶为四方相。衍射研究表明，FeSbO 纳米粒子具有高结晶度和高纯度。此外，通过 XRD、拉曼、XPS、HRTEM 和 FESEM 分析对其他结构性质和形态进行了表征。通过循环伏安法和计时电流法对 FeSbO 修饰 GCE 对 CRBZ 的检测进行了电化学表征。FeSbO/GCE 在 0.01 µmol L 至 64.3 µmol L 的线性范围内表现出线性范围，灵敏度为 0.68 µA cm µM，LOD 为 5.4 nmol L。此外，FeSbO/GCE 在可能的干扰化合物中表现出高选择性。此外，我们预测的 FeSbO/GCE 电极材料在苹果汁和稻田水样中的实际样品中显示出良好的回收率。
