The invention discloses a method for analyzing the content of fluorine ions in dolomite, limestone and lime, which is characterized by comprising the following steps: S1, weighing a certain amount of sample, melting the sample with sodium hydroxide and sodium peroxide, adding water and ethanol to leach the melt, and carrying out dry filtration; and S2, then taking a proper amount of sample solution, adjusting the pH value to 6.5 +/-0.1, and determining the fluorine content in the serpentine by using a fluorine ion electrode method. The invention aims to provide the method for analyzing the content of the fluorine ions in the dolomite, the limestone and the lime, the determination process is simple, rapid and accurate, and the method is an effective and practical method. 本发明公开了一种白云石、石灰石、白灰中氟离子含量的分析方法，其特征在于，包括：S1、称取一定量的试样→用氢氧化钠和过氧化钠熔融样品→加水、乙醇浸取熔融物→干过滤；S2、然后分取适量样品溶液→调节pH值为6.5±0.1→用氟离子电极法测定蛇纹石中氟含量。本发明的目的是提供一种白云石、石灰石、白灰中氟离子含量的分析方法，测定过程简单、快速、准确，是一个有效、实用的方法。
