| Abstract: | The amounts of Copper, Zinc and Lead in vegetable were determined by flame atomic absorption spectrometry, the method was easy, rapid and economical, and the sensitivity precision and selectivity were high. The content of the three elements were 0.5128mg/Kg(for Cu), 0.8023mg/Kg(for Zn), 0.1028mg/Kg(for Pb), respectively, the relative standard deviation was less than1.4% and recovery of 92.3%~97.2%. The result was satisfactory. |
