Abstract

Carbofuran (CRF) is an important pesticide that is widely used in agriculture to achieve economic benefits. However, its high toxicity raises serious concerns about food and agricultural safety. To address this issue, our study proposes an electrochemical sensor for the detection of the oxidized form of carbofuran by applying yttrium iron oxide (YFO) embedded reduced graphene oxide (rGO). The YFO-rGO composite was synthesized via hydrothermal and sonochemical methods and characterized for its structural integrity and electrochemical performances. The precise detection of CRF was facilitated through the application of voltammetry (CV) and amperometry (i-t) techniques. Notably, the resulting YFO-rGO/RDE sensor exhibited exceptional selectivity and sensitivity toward CRF under optimized conditions, with a lower detection limit of 0.018 µM with a broad linear range of about 0.0299–303.5 µM respectively. It also demonstrates consistent repeatability and reproducibility. Practical validation of the sensor was conducted through the analysis of actual food samples, confirming its efficacy in real-world agricultural settings.

期刊介绍： The Process Safety and Environmental Protection (PSEP) journal is a leading international publication that focuses on the publication of high-quality, original research papers in the field of engineering, specifically those related to the safety of industrial processes and environmental protection. The journal encourages submissions that present new developments in safety and environmental aspects, particularly those that show how research findings can be applied in process engineering design and practice. PSEP is particularly interested in research that brings fresh perspectives to established engineering principles, identifies unsolved problems, or suggests directions for future research. The journal also values contributions that push the boundaries of traditional engineering and welcomes multidisciplinary papers. PSEP's articles are abstracted and indexed by a range of databases and services, which helps to ensure that the journal's research is accessible and recognized in the academic and professional communities. These databases include ANTE, Chemical Abstracts, Chemical Hazards in Industry, Current Contents, Elsevier Engineering Information database, Pascal Francis, Web of Science, Scopus, Engineering Information Database EnCompass LIT (Elsevier), and INSPEC. This wide coverage facilitates the dissemination of the journal's content to a global audience interested in process safety and environmental engineering.
