Recent advances in pretreatment and chromatographic detection methods of bisphenol A over the past decade

Bisphenol A (BPA) is a key industrial chemical, primarily used as a monomer for polycarbonate and epoxy resins, and widely found in food contact materials and consumer products. Owing to its well‑documented endocrine‑disrupting properties, the migration and exposure of BPA have attracted considerable attention in food safety and environmental monitoring. In response to rising detection demands and increasingly stringent regulatory limits, recent years have seen continuous development of efficient pretreatment methods coupled with accurate and sensitive detection techniques. This review systematically examines the research progress over the past decade on BPA pretreatment approaches-including conventional liquid‑liquid extraction, solid‑phase extraction, and various emerging microextraction techniques-alongside chromatographic detection methods. The strengths and limitations of each technique are critically assessed, and future prospects for advancing BPA pretreatment and chromatographic detection are also outlined.
