| 摘 要： | 文章建立了火焰原子吸收光谱法测定冰晶石中钾的分析方法。样品用高氯酸溶解后,在标准系列加入与待测试液等量的铝和钠来消除样品中大量铝和钠对钾的干扰,用空气-乙炔火焰测定了样品中的钾,测定结果与火焰光度法一致。检出限为：0.057m g/L,相对标准偏差（RSD）为：3.55%-4.14%,回收率为：98.67%-103.2%。

| Abstract: | A kind of analysis method has been established for the determination of potassium in cryolite by flame atomic absorption spectrometry in the paper.The samples are dissolved with perchloric acid,and then the same amount of aluminium and sodium are added into the standard series to eliminate the interference of a large amount of aluminium and sodium in the samples.Potassium in the samples is determined under air-acetylene flame and the results are consistent with those by flame luminosity method.The detection limit is 0.057mg/L for K.The relative standard deviations（RSD） are 3.55%～4.14%.The recovery rates are 98.67%～103.2%. |
