矿石和冶炼中间产品中铟的测定,通常采用极谱法或光度法。随着近代分析技术的发展,原子吸收法已成为一种广泛使用的分析技术。并应用于矿石中铟的测定,但这些方法大都需要有机溶剂萃取,手续繁杂。文献介绍了不经溶剂萃取的原子吸收法,但该法不适应大量铁、钙存在下微量铟的测定。 Determination of indium in ores and smelter intermediates, usually by polarography or photometry. With the development of modern analytical techniques, atomic absorption spectrometry has become a widely used analytical technique. And used in the determination of indium ore, but most of these methods require organic solvent extraction, complicated procedures. The literature describes the solventless extraction of atomic absorption method, but the law does not meet the large amount of iron, calcium in the presence of trace indium determination.
