| Abstract: | The Pb in rubber nipple was determined by graphite furnace atomic absorption spectrometry.The best conditions were confirmed by the investigation of matrix modifier,ashing temperature,and atomization temperature.Through a series of experiments determined the optimum conditions selected,the results showed that the detection limit was 0.18 μg/L,the average recoveries of 94.2% to 107.5%,and relative standard deviation of 3.86%(n=5).The method was simple,fast,reproducible,high sensitive and accurate. |
