摘要
为控制纯铜中杂质元素的指标,准确测定其中痕量元素铅和铋的含量十分必要。采用铜作为基体改进剂,可提高灰化温度和原子化温度。选择纯铜样品进行试验测定铅和铋的相对标准偏差分别为6.32%和3.53%。石墨炉原子吸收光谱法测定纯铜中痕量铅和铋,方法可靠,简单快速。
In order to control the impurities content in pure copper, it is important to determine trace Pb and Bi in pure copper. The ashized and atomized temperature can be enhanced when Cu is used as a matrix modifier. It is determined to select the pure copper as standard sample. The relative standard deviation of Pb is 6.32%, Bi is 3.53%. It is simple and quick to determine trace Ph and Bi in pure copper using the graphite furnace atomic absorption spectrophotometry.
