摘要
由于双酚 A(BPA)和双酚 S(BPS)等酚类物质具有潜在的健康危害,如荷尔蒙紊乱、代谢紊乱和癌症等,因此检测食品中因塑料包装泄漏而产生的双酚 A(BPA)和双酚 S(BPS)等干扰内分泌的酚类物质至关重要。尽管已开发出多种基于双金属和三金属 MOF 的结构来灵敏地检测这些污染物,但要实现具有多种有效结合位点的高选择性、高灵敏度的混合系统,以同时选择性地监测这些污染物,仍然具有挑战性。为此,我们开发了一种新型电极系统,使用硫脲官能化的三金属(铁、钴和锰)有机框架(S-FCM-MOF)包覆聚己内酯(PCL)电纺纳米纤维。有趣的是,S-官能化增强了对双酚 A 和双酚 BPS 的吸附能力,而 PCL 则提高了基于 FCM-MOF 的电极表面的导电性和电荷密度,从而克服了实现高选择性、高灵敏度混合系统以同时精确检测这些污染物的挑战。这种协同效应导致了对双酚 A 和双酚 S 的高灵敏度(7.0479、5.9249 μA/μM/cm²)、低检测限(2.57、2.91 μM)和宽线性范围(5-365、5-360 μM)。此外,即使存在 Mg²⁺、Zn²⁺、Cu²⁺、NO₃-、KCl、AA、CA、HQ、PNP、KBr 和 MgSO₄等干扰物质,S-FCM-MOF@PCL 电极对双酚 A 和双酚 BPS 也具有高选择性。这种创新设计的电极可有效地用于灵敏/选择性监测塑料袋包装冷冻肉类样品中的双酚 A 和双酚 BPS,且精度高、准确度高,从而确保了我们设计的传感器的可靠性。
Sensitive detection of bisphenol A and S in plastic-packaged frozen meat using trimetallic MOF-coated electrospun nanofibers
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.
