文献提出了用磷酸三丁酯(TBP)-氢溴酸(HBr)体系萃取色层分离微量铟的方法。但是这些资料对铟的萃取色层条件及杂质元素的萃取色层行为均没有详细的介绍。我们进行了以TBP-HBr体系萃取色层分离微量铟的试验。详细地研究了铟的萃取色层条件及铟与20多种阳离子的分离,并拟订了测定矿石中微量铟的操作规程。矿石分析结果表明,本法的选择性、灵敏度和准确度都是良好和符合
The literature proposes a method for the separation of trace amounts of indium by extraction of a color layer with a tributyl phosphate (TBP) -hydrobromic acid (HBr) system. However, these data do not give a detailed description of the conditions of extraction of indium and the extraction of impurity layers. We conducted a TBP-HBr system for the chromatographic separation of trace amounts of indium. The condition of extraction of indium and the separation of indium from more than 20 kinds of cations were studied in detail. A procedure for the determination of trace indium in ore was developed. Ore analysis results show that the selectivity, sensitivity and accuracy of this method are good and consistent
