Abstract

Background

Carbamate insecticides find widespread use in crop protection. Propoxur (PPX) is a type of pesticide classified as a carbamate insecticide, commonly used to control pests in both agriculture and households. The chances of these compounds being present are quite high. For this reason, it is imperative to perform a quantitative analysis of food samples to assess insecticides.

Methods

The development of a sensitive sensor using plate-like metallic silver alloyed copper oxide (m-Ag-CuO) allowed for the detection of PPX in food samples. The physical characteristics of m-Ag-CuO were determined through the use of microscopic and spectroscopic techniques. With its high sensitivity and exceptional selectivity, the electrochemical sensing method provides rapid and accurate results, making it a preferred choice for detect PPX.

Significant findings

The fabricated sensor showed impressive performance under optimal experimental conditions, with a limit of detection (LOD), limit of quantification (LOQ) and a sensitivity are 0.62 ng/L and 1.9 ng/L, and 0.67 µA (ng/L)^–1 cm^–2. We assessed the functionality and suitability of the sensor through selective study and analysis of food samples, achieving a recovery rate of 95 – 102 %. This indicates that the sensor successfully adapted to analyze PPX in different food products.

金属银合金氧化铜电催化剂：食品样品中丙硫杀虫剂的高灵敏度检测平台

背景氨基甲酸酯类杀虫剂广泛用于作物保护。丙溴磷（PPX）是一种被归类为氨基甲酸酯类杀虫剂的杀虫剂，通常用于控制农业和家庭中的害虫。这些化合物存在的几率相当高。因此，必须对食品样本进行定量分析，以评估杀虫剂。方法利用板状金属银合金氧化铜（m-Ag-CuO）开发了一种灵敏的传感器，可以检测食品样本中的 PPX。利用显微镜和光谱技术确定了 m-Ag-CuO 的物理特性。在最佳实验条件下，制备的传感器表现出了令人印象深刻的性能，其检测限（LOD）、定量限（LOQ）和灵敏度分别为 0.62 ng/L 和 1.9 ng/L 以及 0.67 µA (ng/L)-1 cm-2。我们通过对食品样品的选择性研究和分析评估了传感器的功能性和适用性，回收率达到 95 - 102 %。这表明该传感器成功地适用于分析不同食品中的 PPX。
