Abstract

Bisphenol A (BPA) is categorized as an endocrine-disrupting substance; it is a risky substance to both environmental and human health, necessitating monitoring. In this present study, a novel electrochemical sensing platform based on Cd metalloporphyrin ([(5,10,15,20- tetrakis(p-flurophenyl) porphyrinato] cadmium (II) [CdTFPP]) and gold nanoparticles (AuNPs) for a rapid and sensitive determination of BPA was designed. To confirm the successful synthesis of CdTFPP, UV/vis, IR, and ¹H NMR were employed. The detection platform CdTFPP/AuNPs/SPCE was prepared using a screen-printed electrode (SPCE), through the deposition of AuNPs and CdTFPP by drop-casting. Under optimized measuring conditions, the developed sensor exhibited two linear ranges from 10⁻¹⁰ to 10⁻⁷ M and 10⁻⁷ to 10⁻² M with a limit of detection of 133 pM. Additionally, the CdTFPP/AuNPs/SPCE/ electrode demonstrated to present an excellent selectivity and reproducibility and to be a promising tool for the development of simple low-cost water quality monitoring system for BPA detection.

双酚 A（BPA）被归类为内分泌干扰物质，对环境和人类健康都有风险，因此有必要对其进行监测。本研究设计了一种基于镉金属卟啉（[(5,10,15,20- tetrakis(p-flurophenyl) porphyrinato] cadmium (II) [CdTFPP]）和金纳米粒子（AuNPs）的新型电化学传感平台，用于快速灵敏地测定双酚 A。为了证实 CdTFPP 的成功合成，使用了紫外/可见光、红外和 1H NMR。通过滴铸法沉积 AuNPs 和 CdTFPP，利用丝网印刷电极（SPCE）制备了 CdTFPP/AuNPs/SPCE 检测平台。在优化的测量条件下，所开发的传感器具有 10-10 至 10-7 M 和 10-7 至 10-2 M 两个线性范围，检测限为 133 pM。此外，CdTFPP/AuNPs/SPCE/电极还具有极佳的选择性和再现性，是开发简单、低成本双酚 A 检测水质监测系统的理想工具。
