Abstract

This work proposes a sensitive and nonenzymatic electrochemical platform for the cyclic voltammetric determination of ethyl-paraoxon (E-POX) at a poly-bromophenol red (poly(BPR) film coated graphene oxide (GO) and ZnO nanocomposite modified glassy carbon electrode (poly(BPR)@GO-ZnO/GCE). The incorporation of poly(BPR) matrix with GO-ZnO nanocomposite provides a considerable synergistic effect for the voltammetric determination of E-POX by providing a large surface area, more active sites, and high conductivity. The results showed that the poly(BPR)@GO-ZnO/GCE exhibits two linear response ranges from 0.10–3.0 µM and 5.0–200 µM with a limit of detection (LOD) of 31 nM and a high sensitivity of 5259 μA mM⁻¹ cm⁻². Real-world applicability of designed platform was successfully tested in agricultural (tomato and cucumber) and tap water samples, and acceptable recovery values (98.1–114.2 %) were obtained. It is concluded that the proposed platform (poly(BPR), GO, and ZnO) may bring remarkable approaches to the future fabrication of electrochemical sensors.

期刊介绍： The Journal of Food Composition and Analysis publishes manuscripts on scientific aspects of data on the chemical composition of human foods, with particular emphasis on actual data on composition of foods; analytical methods; studies on the manipulation, storage, distribution and use of food composition data; and studies on the statistics, use and distribution of such data and data systems. The Journal''s basis is nutrient composition, with increasing emphasis on bioactive non-nutrient and anti-nutrient components. Papers must provide sufficient description of the food samples, analytical methods, quality control procedures and statistical treatments of the data to permit the end users of the food composition data to evaluate the appropriateness of such data in their projects. The Journal does not publish papers on: microbiological compounds; sensory quality; aromatics/volatiles in food and wine; essential oils; organoleptic characteristics of food; physical properties; or clinical papers and pharmacology-related papers.
