硝酸镉中铁铜锌铅的FAAS快速分析测试技术

Quick Determination of Iron, Copper, Zinc and Lead in CadmiumNitrate by Flame Atomic Absorption Spectroscopy

摘要: 运用FAAS快速分析硝酸镉中铁、铜、锌、铅含量，建立了铁、铜、锌、铅的共振线，灯电流，酸性介质等最佳实验条件.显示出该方法具有很好的灵敏度和材料重现性，具有方法步骤简单、操作容易、干扰少等特点.测定样品铁、铜、锌、铅含量的相对标准偏差均小于1.0%（n=10）.标准加入回收率均在97.0%～98.5% 范围内.适用于硝酸镉中铁、铜、锌、铅的含量控制分析和样品系统分析.

Abstract: Utilizing FAAS the quick determine of Iron, Copper，Zinc and Lead in cadmium nitrate was described. The deviation RSD＜1.0% comparing to standard value. The standard adding recovery is in the range of 97.0%～98.5%. The method was fully suitable to the control of Iron，Copper，Zinc and Lead in cadmium nitrate.
