摘  要:
[目的]建立消解罐消解—火焰原子吸收法测定鱼肉中锌的方法。[方法]样品经消解罐消解后,用火焰原子吸收法测定样品中锌浓度。[结果]该方法在锌浓度为0~2.0mg/L范围有良好的线性关系,相关系数r=0.9997,检出限锌为0.002μg/mL,相对标准偏差为3.12%,回收率锌为95.0%~102.5%。[结论]该方法具有简便、快速、准确等优点,可用于鱼肉中锌的定量检测。

摘  要:
[Objective]To establish a determination method of Zn in fish by digestion tank digestion and flame atomic absorption spectrometry.[Method]The fish was dissolved by digestion tank digestion, and then Zn in fish was determined by flame atomic absorption spectrometry.[Result]This method had good linear relation when the concentration range of Zn was 0-2.0 mg/L, and the correlation coefficient was 0.999 7. The detection limit of Zn was 0.002 μg/mL, with the relative standard deviation of 3.12%. The recovery of Zn was 95.0%-102.5%.[Conclusion]The method is simple, rapid and accurate, so it is suitable for the determination of Zn in fish.
