A Brief Review of Detection and Removal of Bisphenol A in Aqueous Media

2022

Bisphenol A (BPA) is a synthetic monomer applied in the polymeric industry that can contaminate food and water, leading to serious health risks associated with human exposure. The consumption of food and water contaminated with this compound directly affects the endocrine system and increases the susceptibility to cancer. The purpose of this review is to present the main studies dedicated to detection and removal of BPA from aqueous media. The literature reports different ways of detecting BPA in different fluids, such as aqueous solutions, water matrix, and bottled drinks (water, juices, and soft drinks). In addition, the main treatment of these matrixes include adsorption or (photo)degradation processes. Detection techniques include high-performance liquid chromatography (HPLC), gas chromatography (GC), capillary electrophoresis (EC), immunochromatographic assay, and electrochemical sensors. The recent studies discourse about BPA removal includes techniques such as (photo)degradation Fenton, adsorption, peroxidation, oxidation and heterogeneous photocatalysis. For photo-degradation, many semiconductor oxides have been used, which can be active under visible or ultraviolet irradiation. Also, plant-based materials have been used as adsorbate to remove BPA. In general, all available techniques present advantages and disadvantages for determining and removing BPA in aqueous media. In this review, we will discuss the main contributions of recent studies related to the detection and treatment of systems contaminated with BPA.
