火焰原子吸收光谱法测定硫酸锌中的铁
邓自西(湖南化工研究院; 湖南长沙)
摘 要:采用火焰原子吸收光谱法测定硫酸锌中的微量的铁,考察了HCl、SO42-对测定的影响。在选定条件下,方法线性相关系数为0.9998,检测限为0.0072mg/L,标准偏差为0.0008,变异系数为2.0%,回收率为95.2%~104.8%。

Determination of Iron in Zinc Sulfate by FAAS
DENG Zi-xi (Hunan Research Institute of Chemical Indurstry; Changsha 410007; China)
Abstract:A method was discussed for the determination of iron in zinc sulfate with FAAS. The influences of the concentration of hydrochloric acid and SO_(4)~(2-) on the result were studied. The results showed that the standard deviation was 0.0008, the coefficient of variation 2.0%,the recovery 95.2%~104.8%,linear relative coefficient 0.9998,and the detection limit 0.0072mg/L.
Key words:FAAS; zinc sulfate; iron
