A new flow injection chemiluminescence (CL) method has been developed for the determination of bisphenol A (BPA), based on the inhibitory effect of BPA on the chemiluminescence reaction between luminol and potassium hexacyanoferrate. Under optimum conditions, the decrease in CL emission intensity was linear with BPA concentration in the range 8.0 × 10 −7 –1.2 × 10 −5 mol[sol ]L, and the detection limit was 3.1 × 10 −7 mol[sol ]L. The relative standard deviation (RSD) of 11 replicate measurements was 2.6% for 2.0 × 10 −6 mol[sol ]L BPA ( n = 11). The sampling frequency was calculated to be ca. 120[sol ]h. This method has been successfully used to determine the content of BPA in aqueous solution of polycarbonate materials. A brief discussion on the possible chemiluminescence reaction mechanism is presented. Copyright © 2005 John Wiley & Sons, Ltd.
