| 摘 要： | 建立了微波等离子体原子发射光谱法(MP-AES)测定地质样品中的常量和微量元素的方法,四酸(盐酸+硝酸+高氯酸+氢佛酸)消解样品,得出了使用4200 MP-AES仪分析地化认证参考物质中常规金属元素(Ag,Cu,Ni,Pb和Zn)的结果,测定样品结果的相对标准偏差落在±10%范围内,另外,IEC和FLIC模型可成功校正光谱干扰。MP-AES仪无需使用乙炔等危险气体,极大提高了实验室安全性并显著降低了运行成本。MP-AES仪已成功应用于地化样品的分析中,结果准确可靠。

| Abstract: | A determination method for major and minor elements including Ag, Cu, Ni, Pb and Zn was investigated by MP-AES. The sample was pretreated by HNO3-HCl-HClO4-HF. The proposed method was validated by the analysis of geochemical certified reference materials within ±10% standard deviations (SD) In addition, the spectral interference could be corrected by the use of IECs and FLIC models. No dangerous gas such as acetylene adopted in MP-AES methods might greatly improve the laboratory safety and significantly reduce the running costs. It was successfully applied for the analysis of geochemical samples with satisfactory results. |
