Spectrofluorometric Analysis of Bisphenol-A in Drinking Water Bottles

Spectrofluorometric Analysis of Bisphenol-A in Drinking Water Bottles Bisphenol-A (BPA) is of environmental concern due to its ability to act as an endocrine disruptor in humans and many other animals. In the food industry, BPA is widely used in the production of plastic bottles and plastic liners in aluminum cans. Over time, trace amounts of BPA can leach from the container and into the contents inside. A new method of testing for trace amount of BPA involved the formation of an inclusion complex with ß-Cyclodextrin. With the formation of the inclusion complex, it becomes much easier to analyze low concentrations of BPA through the process of spectrofluorometry. A basic calibration curve with BPA/ß-Cyclodextrin standards is used to correlate intensity with BPA concentration. In this research, unopened, disposable water bottles are exposed to varying conditions of temperature and time, and the water inside is analyzed through spectrofluorometry to determine concentrations of BPA. An inclusion complex with ß-Cyclodextrin is helpful in enhancing the detection of BPA when its concentration in the drinking water is below the limit of detection for the spectrofluorometer
