Abstract

The detection and quantitation of bisphenol A (BPA) in the environment and food products has been a subject of considerable interest. BPA, a diphenylmethane derivative is a well-known industrial raw material with wide range of applications. It is a well-known endocrine disruptor and acts as an estrogen mimic. BPA is an environmental health concern and its accumulation in hydro-geological cycles is a matter of serious ecological peril. This review basically assesses various chemically modified electrodes composed of diverse components that have been employed to recognize BPA in different matrices. Electrochemical sensors prepared using graphene materials in combination with metals and polymers for selective detection of BPA have been discussed extensively. The emphasis is on detection of BPA in various samples encountered in routine use such as plastic bottles, receipts, baby feed bottles, milk samples, mineralized water, tissue paper, DVDs, and others. Although research in this field is in the exploratory stage, deeper insights into fundamental studies of sensing systems, fast analysis of real samples and validation of sensors are some of the factors that need major impetus. It is expected that chemically modified electrode-based sensing systems will soon take over as a viable option for monitoring diverse pollutants.

摘要

环境和食品中双酚 A (BPA) 的检测和定量一直是备受关注的主题。BPA是一种二苯甲烷衍生物，是一种广为人知的工业原料，用途广泛。它是一种众所周知的内分泌干扰物，可作为雌激素模拟物。BPA 是一个环境健康问题，其在水文地质循环中的积累是一个严重的生态危险问题。这篇综述主要评估了由不同成分组成的各种化学修饰电极，这些电极已被用于识别不同基质中的 BPA。已经广泛讨论了使用石墨烯材料与金属和聚合物结合制备的用于选择性检测 BPA 的电化学传感器。重点是检测日常使用中遇到的各种样品中的 BPA，例如塑料瓶、收据、婴儿奶瓶、牛奶样品、矿化水、薄纸、DVD 等。尽管该领域的研究处于探索阶段，但更深入地了解传感系统的基础研究、真实样本的快速分析和传感器的验证是需要大力推动的一些因素。预计化学修饰的基于电极的传感系统将很快成为监测各种污染物的可行选择。实际样品的快速分析和传感器的验证是需要大力推动的一些因素。预计化学修饰的基于电极的传感系统将很快成为监测各种污染物的可行选择。实际样品的快速分析和传感器的验证是需要大力推动的一些因素。预计化学修饰的基于电极的传感系统将很快成为监测各种污染物的可行选择。
