Abstract:
Bisphenol A, (BPA), is largely used in the production of epoxy resins and polycarbonate plastics as additive and antioxidant. Approximately one million tons of BPA where used only in EU annually. From municipal wastewater and industrial discharge, large quantity of BPA of introduced into the aquatic environment. For determination of bisphenol A in environmental water most frequently used methods are based on liquid chromatography and gas chromatography. As BPA is a phenolic compound, its volatility is relatively low, resulting in poor sensitivity and peak tailing using gas chromatography. To improve analytical performances derivatization is necessary. Stehmann and Schröder previosy studied derivatization of BPA with trifluoroacetic anhydride (TFAA) and characterized formed derivative by massspectra, infrared-spectra and the results of the NMR spectroscopy, but no analytical method for BPA using derivatization with TFAA was developed.
