| Abstract: | The method for the determination of micro Pb in preserved egg by flame atomic absorption spectrometry was studied in this paper. These samples are treated with ammonium persulfate, it is not necessary to preconcentrate the lead by extraction, the method is sensitive, easy to operate and has good precision and accuracy. The detection limit was 0.016 microgram.mL-1, the relative standard deviation of Pb was 3.2%, and the rates of recovery were 94.0%-98.0%. |
