单矿物中微量铟过去多以比色法测定,分析流程较长,难以适应找矿工作的需要,为了提高分析速度,我们在文献的基础上,对方铅矿单矿物中铟用原子吸收法进行了测定。结果表明原子吸收法测定铅单矿物中的微量铟,分析速度快,方法再现性也好;溶液中存在大量铅,对微量铟测定没有影响。 In the past, trace amounts of indium in single minerals were determined by colorimetry. The analysis process was long and difficult to meet the needs of ore prospecting work. In order to improve the analysis speed, on the basis of the literature, indium in galena single mineral was determined by atomic absorption spectrometry The determination. The results show that atomic absorption spectrophotometry can be used for the determination of trace indium in lead single mineral. The method has the advantages of fast analysis and good reproducibility. Large amount of lead is present in the solution, which has no effect on trace indium.
