Abstract:A simple,rapid method for the determination of bisphenol A in plastic product extracts was developed by ultrasonic extraction coupled with fluorophotometry.Parameters that affect the extraction efficiencies and determination were investigated.Under the optimum conditions,the proposed method is sensitive and shows a good linearity within a range of 0.5-25 mg/L,with the correlation coefficients(r) is 0.999 6,The limits of detection(LODs) was 0.2 mg/L,the recoveries of the target analytes from four different samples was 91.1% ~100.4%,the relative standard deviations(RSDs,n=10) were below 4.3%.The proposed method was applied successfully to the determination of BPA in the plastic samples.
Keywords:ultrasonic extraction  fluorophotometry  bisphenol A  plastic product extracts
