摘要
本文介绍了利用塞曼石墨炉原子吸收法直接测定硝酸银中的杂质锰、镍、铜、铁和铬。方法简单、快速、检出限低、回收率好。
The method of direct determination of mangenese, nickel, copper, iron and chromium in silvernitrate by Zeeman graphite furnace atomic absorption spectrometry (GFAAS) is described in thisPaper. This method is simple, quick and accurate. The detection limits are low and the recoveriesare satisfactory.
