摘要
采用硝酸和高氯酸(4+1)消解样品,火焰原子吸收光谱法测定火龙果果肉、果皮中Fe、Mn、Zn微量元素的含量。结果表明:火龙果果肉中Fe、Mn、Zn含量分别为104.8μg/g、23.95μg/g、66.40μg/g,果皮中Fe、Mn、Zn含量分别为52.15μg/g、129.6μg/g、80.3μg/g。回收率在95.15%～104.5%之间,RSD小于1.6%,结果满意。
The nitric acid and perchloric acid （4 ＋ 1 ） mixed acid digestion and flame atomic absorption spectrometry dragon fruit pulp, peel Fe, Mn, Zn trace elements. The results showed that： dragon fruit pulp containing Fe, Mn, Zn contents were 104.75μg/g, 23.95 μg/g, 66.4 μg/g, peel containing Fe, Mn, Zn, respectively 52.15 μg/g, 129.65 μg/g , 80.3μg/g. Recovery of 95.15 % - 104.5 % between, RSD less than 1.6 %, with satisfactory results.
