Abstract
Detecting endocrine-disrupting phenolic substances like bisphenol A (BPA) and bisphenol S (BPS) in food products due to leakage from plastic packaging is crucial due to their potential health hazards such as hormonal disruption, metabolic disorders, cancer etc. Despite a wide range of bimetallic and trimetallic MOF-based structures have been developed for the sensitive detection of these pollutants; however, achieving a highly selective and sensitive hybrid system with diverse and effective binding sites for simultaneous and selective monitoring of these pollutants remains challenging. To address this, herein we developed a novel electrode system using thiourea functionalized trimetallic (Fe, Co, and Mn) organic framework (S-FCM-MOF) coated polycaprolactone (PCL) electrospun nanofibers. Interestingly, the S-functionalization enhances adsorption capacity for BPA and BPS, whereas PCL improves electrical conductivity and charge density across the FCM-MOF-based electrode surface, thus overcoming the challenge of achieving a highly selective and sensitive hybrid system for the simultaneous and precise detection of these pollutants. This synergistic effect leads to high sensitivity (7.0479, 5.9249 μA/μM/cm²), low detection limits (2.57, 2.91 μM), and wide linear ranges (5–365, 5–360 μM) against BPA and BPS, respectively. Furthermore, the S-FCM-MOF@PCL electrode demonstrates high selectivity for BPA and BPS even in presence of interfering species including Mg²⁺, Zn²⁺, Cu²⁺, NO₃⁻, KCl, AA, CA, HQ, PNP, KBr and MgSO₄. This innovative designed electrode is effectively used for sensitive/selective monitoring of BPA and BPS from plastic bag-packaged frozen meat samples with high precision and accuracy, thus ensuring the reliability of our designed sensor.
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.
