摘　　要：目的探讨黑色食品中铜、锌、铁、钙的测定方法。方法将样品进行微波消解,用火焰原子吸收法测定黑色食品中的铜、锌、铁、钙。结果本方法相关系数为0.999 3～1.000 0,RSD为0.93%～2.83%,加标回收率98.6%～106.3%。结论用本方法测定黑色食物中的微量元素,操作简单快速,结果准确。Objective To explore a method for determination of trace elements in black food. Methods Microwave diges- tion- flame atomic absorption spectrometry was used to measure copper, zinc, iron and calcium in black food. Results The correlation coefficient of the method was between 0. 999 3 and 1. 000 0, the relative standard deviation （RSD） was 0. 93% -2. 83% , the recovery rate was 98.6% - 106. 3%. Conclusion The method is simple and rapid, the result is accurate.
