摘　　要：目的建立火焰原子吸收光谱法测定保健食品中镁的分析方法。方法样品用硝酸和高氯酸消化后,导入火焰原子吸收分光光度计中,与标准系列比较定量。结果方法的检出限为0.017μg/m l,相对标准偏差为0.72%~1.86%,加标回收率在96.9%~104.6%之间。结论该法操作简便、快速、准确,适用于保健食品中镁的测定。[Objective]To establish a method for determining health food by flame atomic absorption spectrometry.[Methods]After the nitric acid and the perchloric acid digestion,the sample was induced in the flame atomic absorption spectrometry with standard series comparison quantitative.[Results]The detection limit was 0.017 μg/mL,The RSD was 0.90%~2.07%,The recovery was in the range of 96.9%~104.6%.[Conclusion]This method is simple,rapid,accurate,and suitable for measuring magnesium in health food.
