Abstract: Anew method is reported for the determination of trace amount of Pb(Ⅱ) with Lucigenin-H2O2-Pb(Ⅱ) chemiluminescence system by F1A. The detection limit of the method is 0. 5 μg/mLfor Pb(Ⅱ). If the range of Pb(Ⅱ) concentration for the working curves was 0-100 μg/mL, the peak height was found to be linearly dependent on the concentration of Pb(Ⅱ). The relative standard deviation is less than 1.9%. The method was applied to determination of Pb(Ⅱ) in waste water with satisfactory results.
