石墨炉原子吸收法与火焰原子吸收法对地表水中铜离子的监测对比

Comparison Between Graphite Furnace Atomic Absorption Spectrometry and Flame Atomic Absorption Spectrometry in Monitoring Copper Ion in Surface Water

铜离子是人体所必须的微量元素。但是地表水中的铜含量是有一个固定的值的,一旦超出固定值就会对水中的生物产生一定的影响。当前一些主要的铜污染多半来自于那些石油化工、冶炼五金以及化学工业等企业所排放的污水,因此,要对地表水中的铜离子进行监测。文章的主要内容是石墨炉原子吸收法与火焰原子吸收法对地表水中铜离子的监测情况进行对比分析。

Copper ion isa necessary trace element for human body. But the copper content in the surface water has a fixed value, once exceeded the fixed value, it will have a certain impact on the organisms in the water. At present, most of the major copperpollution comes from the sewage discharged from petrochemical, metal smelting and chemical industries. Therefore, it is necessary tomonitor the copper ions in surface water. The main content of this paper is to compare and analyze the monitoring of copper ions insurface water by graphite furnace atomic absorption spectrometry （GFAAS） and flame atomic absorption spectrometry （FAAS）.
