原子捕集火焰原子吸收光度法测定镍和铜的研究和应用

The Study and Application of Determining Nickel and Copper by Flame Atomic Absorption Spectrometry Using Trapping Technique

本文报道了采用狭缝石英管原子捕集器火焰原子吸收光度法测定镍和铜的最佳条件、灵敏度、检出限、精密度和线性范围。应用该技术测定人发样品中的镍和铜。

In this paper,in AIR/C2H2 flame,the optimum condition of the determination of Ni and Cu were studied,using the slotted tube atom trap as ground\|state atom collector. Ni and Cu in human hair sample was determined directly by flame atomic absorption spectrometry using an atom trapping technique.The results were satisfactory.
