摘要:

锂精矿是一种含有高品位锂的天然矿物,且含有丰富的铷和铯,准确测定3种元素含量具有重要现实意义。采用四酸溶解锂精矿,在稀硝酸介质中,采用原子吸收光谱法测定锂精矿中的锂、铷、铯含量。本方法准确度高、精密度好,加标回收率为98.67 %~99.67 %,测定结果的相对标准偏差均小于5 %,且与国标法测定结果一致,可用于行业推广。

Abstract:

Lithium concentrate is a natural mineral grade a high grade of lithium,as well as abundant rubidium and cesium.Accurate determination of the content of these 3 elements is of great practical significance.Tetra-acid sample dissolution was used to dissolve lithium concentrate,and the content of lithium,rubidium,and cesium in lithium concentrate was determined by atomic absorption spectrometry in a dilute nitric acid medium.This method has high accuracy and good precision,with a spike recovery rate of 98.67 %-99.67 %.The relative standard deviations of the measurement results were all less than 5 %,and they were consistent with the results obtained by the national standard method,making it suitable for industry promotion.
