Metallic silver-alloyed copper oxide electro-catalyst: A high-sensitivity platform for propoxur insecticide detection in food samples
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.
期刊介绍：
Journal of the Taiwan Institute of Chemical Engineers (formerly known as Journal of the Chinese Institute of Chemical Engineers) publishes original works, from fundamental principles to practical applications, in the broad field of chemical engineering with special focus on three aspects: Chemical and Biomolecular Science and Technology, Energy and Environmental Science and Technology, and Materials Science and Technology. Authors should choose for their manuscript an appropriate aspect section and a few related classifications when submitting to the journal online.
