摘要
建立了电感耦合等离子体发射光谱法(ICP-AES)测定萤石中碳酸钙的新方法,对该方法的检出限进行了实验。同时,对该方法进行了精密度实验,相对标准偏差均小于2.5%,样品的加标回收率均在97%~103%之间。该方法缩短了分析时间,消除了经典化学分析方法中氟化钙同时被溶解的问题。
A new determination method of calcium carbonate in fluorite by inductively coupled plasma-atomic emission spectrometry( ICP-AES) was established in this paper. The detection limit of the method was also tested. The precision test result was that the relative standard deviation was less than 2. 5%,and the spiked recoveries of the samples were from 97% to 103%. The new method shortens the analysis time and eliminates the problem of calcium fluoride dissolution in the classical chemical analysis method.
