| Abstract: | A new spectrofluorimetric method has been developed for the determination of bisphenol A based on the inhibitory effect of bisphenol A on redox reaction between hydroxyl radical and acridine orange in acidic media.This method is simple,fast,and its linear range is 1.0 to 100 ng/mL with the detection limit of 0.21 ng/mL.The proposed method was applied to the determination of bisphenol A in plastic bag with satisfactory results. |
