| Abstract: | The atomic fluorescence method is used to assay the lead in vegetables. The result shows that the minimum detection limit is 0. 16μg/L. The linear relation is good, and the relative standard deviation is 0.9995. By the coefficient recoveries to inspect the accuracy, the coefficient recoveries are from 94.5% - 103.7%. By the relative standard deviation to inspect the precision, the relative standard deviation is always below 4.0%. |
