摘　　要：目的建立火焰原子吸收法测定硫酸锌片中锌的含量。方法采用火焰原子吸收法,检测波长为213.9 nm,灯电流为8 mA,狭缝宽度为0.7 nm,燃气流量为2 L.min-1,助燃气流量为8 L.min-1。结果 Zn的浓度在0～2.0μg.mL-1线性关系良好,相关系数为0.999 8,平均加样回收率为99.0%(RSD=0.4%,n=6)。结论所建立的火焰原子吸收法可控制硫酸锌片中锌的含量,灵敏度高。Objective To establish an flame atomic asorptionspectrometry method for the determination of Zn in Zinc sulfate tablets.Methods The determination wavelength was 213.9 nm,the electric current of the light was 8 mA,the slit-width was 0.7 nm,the flow rate of burning gas was 2 L.min-1and the flow rate of gas to help burn was 8 L.min-1.Results The good linear relation was determined at 0-2.0 μg.mL-1 by flame atomic asorptionspectrometry with a regression coefficient of 0.999 8.The average recovery was 99.0%（RSD = 0.4%,n = 6）.Conclusion Flame atomic asorptionspectrometry,a simple,accurate and sensitive method,may be used to control the quality of Zinc sulfate tablets.
