Abstract
Gas chromatography/mass spectrometry (GC/MS) is generally used for analysis of bisphenols in field environments. However, there are the cases that the sensitivity is not enough to determine their concentration. In this work, a liquid-chromatographic determination based on intramolecular excimer-forming fluorescence derivatization with a pyrene reagent, 4-(1-pyrene)butyryl chloride was examined for the analysis of bisphenol A in river waters. This method is highly selective and sensitive fluorometric method for biogenic related compounds, polyamines, polyphenols and dicarboxylic acids though it has never been applied for analysis of bisphenols in field environments. With the method, we determined concentrations of bisphenol A in waters sampled form 6 rivers in Shizuoka Prefecture. As a result, the values determined were ranged from 0.0016-0.17μg/L. They agreed with those determined by conventional method with GC/MS.
