| 摘 要： | 用浓硝酸与高氯酸混酸消解植物叶，其中铜、锌及锰含量较高，可直接用火焰原子吸收光谱法测定；铅、镉及铬含量较低，用石墨炉原子吸收光谱法测定；铅和镉含量甚微，受基体及共存元素干扰严重，用标准加入法消除干扰。

| Abstract: | Leaf-sample was digested with conc.HNO3 and HClO4.The elements with high contents(Cu,Zn and Mn) were determined by FAAS,while those with low contents(Pb,Cd and Cr) were determined by GF-AAS.To eliminate the matrix interference and interferences of some co-existing elements,standard addition method was used in the determination of Lead and cadmium. |
