| Abstract: | The paper discussed the determination of trace lead in drinking water by the adoption of Zeeman effect of graphite furnace atomic absorption method,and studied the temperature raising procedure of graphite furnace as well as the effects of matrix modifier on the determination.The measurement results shows that the application of Zeeman background absorption method and the use of HNO 3 as matrix modifier can greatly reduce the matrix disturbance in the water sample,obtaining over 97% of the rate of recovery,thus satisfactory determination results are achieved. |
