地质材料稀土元素的X射线荧光分析文献评介

Review on the Literature of X-Ray Fluorescence Analysis of Rare Earth Elements in Geological Materials

稀土元素分析一直是无机分析化学的热门课题,在相当长的一段时间内也是一大难题。20世纪六、七十年代白云鄂博多金属稀土矿物质组成的研究热潮和七、八十年代痕量稀土元素地球化学的研究热潮有力推动了我国地质材料稀土元素分析技术的发展。文章先从我国稀土元素分析专著、稀土矿石国家一级标准物质、国家标准分析方法和稀土元素分析评述论文等方面评介了我国稀土元素文献及稀土元素分析的基础条件概况。文章收集了国内1964年至2018年以来X射线荧光分析地质材料中稀土元素的部分文献,从矿石矿物中稀土元素和各类地质材料中的痕量稀土分析和矿石矿物中稀土元素的微区原位分析三方面对文献作了重点评介。简介了X射线荧光分析在早期稀土矿石矿物中稀土分量测定的历史贡献,最后讨论了X射线荧光在当今地质材料稀土元素分析中的现存问题并对未来发展提出建议。

The analysis of rare earth elements had been a hot topic in inorganic analytical chemistry,and it was also a big problem for a long time.In the 1960s and 1970s,the research upsurge in the composition of complex polymetallic rare earth minerals in Bayan Obo and the research upsurge in the geochemistry of trace rare earth elements in the 1970s and 1980s greatly promoted the development of rare earth element analysis technology of geological materials in China.In this paper,the literature of rare earth elements in China and the basic conditions of rare earth element analysis were reviewed from the aspects of Monographs on rare earth element analysis,national standard reference materials for rare earth ores,national standard analysis methods and review papers on rare earth element analysis.In this paper,63 papers on XRF analysis of rare earth elements in geological materials from 1964 to 2018 in China were collected.The papers were mainly reviewed from three aspects:analysis of rare earth elements in ore minerals,trace rare earth elements in various geological materials and micro area in situ analysis of rare earth elements in ore minerals.In this paper,the historical contribution of XRF to the determination of REE in early rare earth ores and minerals was briefly introduced.Finally,the existing problems of XRF in the analysis of rare earth elements in geological materials are discussed and suggestions for future development were put forward.There were 126 citations in this paper.
