Bisphenol A (BPA), a synthetic compound widely used in plastics and epoxy resins, is a well-documented endocrine-disrupting chemical (EDC) that interferes with hormonal systems by mimicking or antagonizing endogenous hormones. Its ability to bind to estrogen receptors has raised significant concerns regarding its association with reproductive disorders, developmental abnormalities, metabolic syndromes, and carcinogenesis. Due to its pervasive presence in industrial effluents, landfill leachates, and consumer products, BPA frequently contaminates aquatic environments via wastewater discharge, posing risks to ecosystems and human health. Accurate measurement of BPA in environmental matrices, such as water and wastewater, is critical for assessing exposure levels, understanding contamination pathways, and formulating regulatory policies. The current work has developed a new analytical method based on the microextraction technique, which uses monolithic membrane fiber to extract BPA from environmental samples. The monolithic membrane fiber was prepared via phase inversion. In this study, the following factors were investigated and optimized: the chemical and physical nature of the fiber, extraction time, extraction temperature, pH of the sample solution, salting-out effect, and the type and volume of the desorption solvent. According to the obtained values, the calibration curve has two linear ranges. The first linear range is 1–25 μgL−1, and the second one is 25–150 μgL−1; the limit of detection (LOD) was obtained as 1 μgL−1. The developed analytical method was used to measure BPA in mineral water samples and paper receipts of bank ATMs. The recovery percentages were 93.32% and 95.72%, respectively, which indicates the ability of the proposed method to measure BPA in different real samples without matrix effect.
