| Abstract: | The research on influence of sample acidity and different graphite tubes on the determination of trace lead was carried out.The sawage samples were dissolved and distilled to dryness.And then,joined with the standard solution for nitrate concentration of the same capacity,a high-density graphite tube,deuterium lamp deduction background Graphite Furnace Atomic Absorption Spectrometry method was used to determine trace lead in samples.The recovery rate is 89.6%~102.5%. |
