ABSTRACT BACKGROUND The fluorine content in lithium mica is very high 1． 36 to 8． 71 ，and the leaching rate of lithium during roasting lithium mica minerals decreases gradually with the increase of fluorine content． With increased defluorination of lithium mica，the leaching rate of lithium is also increased accordingly． Therefore， accurate determination of fluorine in lithium mica and control of fluorine content can provide a basis for determining the process conditions，equipment parameters and cost of roasting process． At present，the most common used for determination of fluorine is the ion selective electrode ． However，the process is complex，the analysis time is long and the blank value is high． X- ray Fluorescence Spectrometry XRF is a green and pollution- free ，which is simple，fast and accurate． OBJECTIVES To determine the fluorine content in lithium mica． S The fluorine content in lithium mica was determined by XRF with pressed- powder pellets． The working curve was made from standard material lithium ore and manually prepared calibration material，and the experience coefficient was used to correct the matrix effect and spectral interference． RESULTS The precision RSD， n 10 is 1． 03 and the detection limit of fluorine is 46 4μg/g． Analytical results of samples synthesized from standard samples acquired by this are in good agreement with theoretical values． It is demonstrated by actual samples that the determination results are consistent with those of the ion selective electrode ． CONCLUSIONS This is suitable for determining fluorine in lithium mica with contents ranging from 0． 68 to 9． 14． KEY WORDSlithium mica;fluorine;experience coefficient correction;pressed- powder pellets;X- ray 檱檱檱檱檱檱檱檱檱檱檱檱檱檱檱檱檱檱檱檱檱檱檱檱檱檱檱檱檱檱檱檱檱檱檱檱檱檱檱檱檱檱檱檱檱檱 Fluorescence Spectrometry 关于出版国际 SCI 期刊 X － Ray Spectrometry 中国专辑的征文通知 X － Ray Spectrometry ， ISSN 0049 － 8246， 是由 Wiley 出版集团出版发行的国际 SCI 期刊。根据 X － Ray Spectrometry 编委会讨论商定， 拟于 2019 年出版X － Ray Spectrometry 中国专辑。现中国地质学 会岩矿测试技术专业委员会组织征集符合 X － Ray Spectrometry 标准和范围的中国作者英文论文。凡未公 开发表， 采用 X 射线光谱技术开展的理论、 应用及仪器研发论文均可投稿。 投稿邮箱 ykcs_zazhi163． com。请在邮件标题中注明 X － Ray Spectrometry 投稿。 收稿截止时间 2019 年 6 月 30 日 67 第 1 期 岩矿测试 http ∥www． ykcs． ac． cn 2019 年 ChaoXing
