    Research Progress on Analysis Techniques of Calcium Fluoride in Fluorite

    • 摘要: 萤石中氟化钙在多个行业中应用广泛,其测定方法目前仍以乙二胺四乙酸(EDTA)滴定法为主。近二十年,随着新仪器的深度应用,电感耦合等离子体原子发射光谱法(ICP-AES)、X射线荧光光谱法(XRF)等新型测定方法逐步发展起来。为此,综述了萤石中氟化钙分析测试技术的研究进展,系统归纳总结了该物质测定的技术路线、前处理方法、测定方法、技术原理及干扰与消除等,分析评述了各方法的优劣,同时简述了国内外相关测定标准方法,并对分析技术的未来发展趋势进行了展望(引用文献83篇)。

       

      Abstract: Calcium fluoride in fluorite is widely used in several industries, and its determination methods are still based on ethylenediaminetetraacetic acid (EDTA) titration. In the past two decades, with the deep application of new instruments, new determination methods such as inductively coupled plasma atomic emission spectrometry (ICP-AES) and X-ray fluorescence spectrometry (XRF) have been developed. To this end, the research progress in analytical testing techniques for calcium fluoride in fluorite was reviewed, and the technical routes, pretreatment methods, measurement approaches, technical principles, as well as interference and elimination for this substance were systematically summarized. The advantages and disadvantages of various methods were analyzed and evaluated, and relevant domestic and international determination standard methods were also briefly described. The future development trends of analysis techniques was prospected (83 ref. cited).
