چکیده انگلیسی
Bisphenol A (BPA) is known as endocrine disrupting compound and it is widely used as an intermediate in manufacturing of polycarbonate and epoxy resins. These resins are used to manufacture inner surface of food cans or directly contact with food and can release BPA into food. It is known that BPA poses health risk, but how risky is a matter of debate. In this study, selective and sensitive fluorescent polymeric membrane sensor for detection of BPA was developed based on fluorescence quenching (λex/λemâ¯=â¯272/295â¯nm). Working concentration range was linear between 4.4â¯Ãâ¯10â9 mol Lâ1 and 1.1â¯Ãâ¯10â7 mol Lâ1 with a detection limit of 1.58â¯Ãâ¯10â9 mol Lâ1. Optimization of sensor was done and the sensor exhibited satisfactory results for being used as a fluorescent sensor for determination of BPA. Additionally, the proposed method was successfully applied to plastic food containers real samples. The developed sensor was shown to be more sensitive than other methods currently in use, and was able to provide results in a matter of seconds, opening up the possibility of a rapid tool for BPA detection.
