| Abstract: | A new method for the determination of trace Lead in wine by "HGAFS" is established. The effect of medium, generation of hydride and interference of ions have been discussed. The method shows its high sensitivity and selectivity. Under optium conditions, the detection limit is 0 2 ng /ml, and the linear range is 0-120 ng/ml. More than ten of usual elements where exist in wine have no effect on the measurement of trace lead. |
