目的:建立火焰原子吸收光谱法测定葡萄糖酸锌颗粒中锌的含量。方法:用盐酸(1:1)溶解样品,以火焰原子吸收法测定锌,从而求得葡萄糖酸锌颗粒中锌的含量。结果:锌在4.0～20.1μg·ml~(-1)范围内,浓度与吸光度呈良好线性关系(r= 0.999 9),平均回收率为99.0%,RSD为1.4%(n=5)。结论:本方法简便,准确、重复性好。 Objective: To establish a flame atomic absorption spectrometry method for determination of zinc in zinc gluconate granules. Methods: Samples were dissolved with hydrochloric acid (1: 1) and zinc was determined by flame atomic absorption spectrometry to determine the content of zinc in zinc gluconate granules. Results: The concentration of zinc in the range of 4.0-20.1μg · ml -1 showed a good linear relationship with absorbance (r = 0.999 9). The average recovery was 99.0% and the RSD was 1.4% (n = 5). Conclusion: The method is simple, accurate and reproducible.
