原子吸收分光光度法测定矿石中的铟、铊国内许多单位早已做过工作。我们在他们的基础上试图找出我们自己的比较合适的分离,富集条件并拟定出测定方法。资料介绍的于溴化物—硫酸介质中用甲基异丁基酮萃取铟及三价铊、并用有机相直接进行原子吸收测定的方法是比较简便的,但为了使一价铊氧化成容易被萃取的三价铊,使用了刺激性强的饱和溴水不太理想,为此资料认为在一定量的三价铁的存在下,不用溴水同样能达到使铊氧化的目 Atomic absorption spectrophotometric determination of indium ore, thallium many units have long been done work. On their own basis, we try to find our own suitable separation, enrichment conditions and to develop a method of measurement. Data described in the bromide - sulfuric acid medium with methyl isobutyl ketone extraction of indium and trivalent thallium, and the organic phase with direct atomic absorption determination method is relatively simple, but in order to monovalent thallium oxidation can be easily extracted Of the trivalent thallium, the use of strong irritating saturated bromine water is not ideal, this data that in the presence of a certain amount of ferric, bromine can also achieve the same purpose of oxidation of thallium
