摘　　要：硝酸—高氯酸(4:1)混酸分解竹叶样品,原子吸收光谱法测定竹叶中的Cu、Fe、Zn、Ni、Pb、Cd、Cr等7种微量元素,并比较了不同地区的竹叶中微量元素的含量。结果表明,竹叶中7种微量元素含量差异显著,其中Cu、Fe和Zn的含量较高,Ni、Pb次之,Cd和Cr最低,可为竹叶的质量评价提供参考依据。Bamboo leaf were resolved by Mix acid（ nitric acid： perchloric acid = 4：1 ）. Seven trace elements including Cu, Fe, Zn, Ni, Pb, Cd,Cr in bamboo leaf were determined by atomic absorption spectroscopy. At the same time, we determined seven trace elements of bamboo leaf from different areas. The results show there is significant difference in the contents of seven trace dements of the leaves of bamboo. The highest content dements are Fe and Zn, then Cu, Ni, Pb, last Cr and CA.
