Abstract: | objective: To determination of Fe, Cu, Mn in h. cordata rhizome leaves, the content of four trace elements in Pb. Methods: Nitric acid and perchloric acid (4 + 1 ) decomposition of samples, flame atomic absorption spectrometry. Conclusion: H. cordata rhizome leaves in four kinds of trace elements is different, element content in the root of size: Fe 〉 Mn 〉 Cu 〉 Pb. Stems of content is: Fe 〉 Mn 〉 Cu〉 Pb. In the leaf content: Fe〉Mn〉Pb〉Cu. Recovery rate was between 94.5% -104.4%, RSD 〈2.9%. |
