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．
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.
