Ammonia Mediated Silver Nanoparticles Based Detection of Bisphenol A, an Endocrine Disruptor, in Water Samples after Vortex-Assisted Liquid–Liquid Microextraction

Bisphenol A (BPA), an alkylphenolic compound, is one of the most polluting and hazardous organic chemicals. Its routine detection is, however, still rather expensive due to high-cost equipment. In this context, we applied effect caused by BPA optical properties surfactant-stabilized silver nanoparticles further modified with use ammonia (AgNP-NH3) develop a simple quantitative approach for determination. The experimental conditions AgNP-NH3 probe were adjusted establish stable sensitive response toward in aqueous media. dispersion measured at wavelength 403 nm enabled limit 2.0 nmol L−1 (0.5 ng mL−1), linear as function concentration ranging from 10 120 (from 2.2 27 mL−1). vortex-assisted liquid–liquid microextraction ensured application selective determination real tap stream water samples, recoveries 85.0 111%. protocol developed herein simple, sensitive, selective, does not require toxic labeling agents, can be easily adapted analysis different samples.
