| Abstract: | A microwave digestion method was used in treatment of milk samples to determine lead conten. This method has the advantages of simple operation, less error. The lead in treatment solution was detected by atomic absorption spectrometry. The linear range of standardcurve was 0 to 40 ng/mL and the correlation coefficient was 0.9998. The recovery rates in milk lead were 90% to 95%. This method is not only exact and less error but also improving the detection efficiency. |
