Abstract:

We applied ICP-AES to the determination of Sn, Pb, Fe and Zn in copper ally. We obtained the dissolving method of the four metals by experiments, which were employed to prepare standard reserve supply liquid. We also analyzed the effect of acid on the formation of metastannic acids precipitation and optimized the parameters of the instrument and its analysis spectral line. The precision and accuracy of the analytic results of the standard samples were satisfactory, as compared with the standard sample value.

Key words: ICP-AES, copper ally, Sn, Pb, Fe, Zn
