发射光谱法因具有多元素同时测定,分析速度快,灵敏度高,检出限低,使用方便的特点,被用于地质样品中银及其他痕量元素的测定。随着我国地质勘查事业的发展和地球化学调查工作力度的加大,对覆盖区的多目标地球化学调查样品的测试及质量控制提出了更高的要求。同时分析方法和测试技术有了新的进展。基于蒸馏原理的电弧光谱测试技术也有了多方面的进展。本论文归纳总结了国内主要刊物上所发表的电弧蒸馏光谱法测定地球化学样品中银及其他痕量元素的研究和应用情况,重点就固体缓冲剂的组成成分进行简要概述,以期为今后样品测试提供参考。
Emission spectrometry has been used for the determination of silver and other trace elements in geological samples due to the simultaneous determination of multiple elements, fast analysis, high sensitivity, low detection limit and easy to use. With the development of geological prospecting and geochemical investigations in our country, more requirements are put forward for the testing and quality control of multi-objective geochemical survey samples in the covered area. At the same time, analytical methods and testing techniques have made new progress. There are many advances in arc spectrometry based on distillation principle. This dissertation summarizes the research and application of arc distillation spectrometry for the determination of silver and other trace elements in geochemical samples published in the major domestic journals, with a brief overview of the composition of the solid buffer in order to provide future sample testing reference.
